AQA A-Level English Language: Child Language Development and Language Change

AQA A-Level English Language (7702) is a specification that rewards students who can combine precise linguistic knowledge with confident data analysis. Two of the most content-heavy topics on the course are child language development and language change. Each one demands a solid grasp of terminology, theories, and frameworks -- and the ability to apply them under timed conditions.

This guide covers both topics in detail: child language development as assessed in Paper 1 Section B, and language change as assessed in Paper 2 Section A. Whether you are revising from scratch or consolidating what you already know, working through these areas methodically will put you in a strong position for the exam.

How These Topics Fit Into the Exam

Before diving into the content, it is worth understanding exactly how these topics are assessed.

Paper 1: Language, the Individual and Society is a 2 hour 30 minute exam worth 100 marks (40% of the A-Level). Section A deals with textual variations and representations, while Section B focuses on children's language development. You will answer one discursive essay question, typically requiring you to evaluate a statement about how children acquire language. You may be given data -- such as a transcript of a child's speech -- which you are expected to analyse using linguistic frameworks and relevant theories.

Paper 2: Language Diversity and Change is also a 2 hour 30 minute exam worth 100 marks (40% of the A-Level). In Section A, you choose either a language diversity question or a language change question. If you choose the language change option, you will write an essay exploring how and why the English language has changed over time, drawing on your knowledge of historical developments, key concepts, and theoretical perspectives.

The remaining 20% of the A-Level comes from the Non-Exam Assessment (the language investigation and original writing).

Part One: Child Language Development (Paper 1, Section B)

Stages of Language Development

Children's spoken language develops through broadly predictable stages. Examiners expect you to know these stages and to use them as a framework when analysing transcript data.

Pre-verbal stage (0--12 months)

Before producing recognisable words, babies experiment with sound in several ways:

Cooing (around 6--8 weeks) -- soft, vowel-like sounds such as "ooo" and "aaa." These are often produced in response to a caregiver's voice.
Babbling (around 6 months) -- consonant-vowel combinations such as "ba-ba" or "da-da." Babbling becomes increasingly varied and begins to reflect the intonation patterns of the child's native language. Reduplicated babbling (repeating the same syllable) typically precedes variegated babbling (mixing different syllables).
Proto-words (around 9--12 months) -- consistent sound sequences that a child uses with apparent meaning, even though they are not recognisable adult words. A child might say "nana" to mean a specific toy, for example. These bridge the gap between babbling and true first words.

Holophrastic stage (12--18 months)

Children begin using single words to convey whole ideas. The word "milk" might mean "I want milk," "where is the milk?" or "I have spilled the milk," depending on context and intonation. These single-word utterances are called holophrases. Vocabulary at this stage typically ranges from around 10 to 50 words.

Two-word stage (18--24 months)

Children start combining two words to express basic semantic relationships: "daddy gone," "more juice," "big dog." These utterances follow recognisable patterns -- agent + action, action + object, possessor + possession -- showing that children are not simply imitating but applying early grammatical rules.

Telegraphic stage (24--36 months)

Utterances grow to three or more words but still omit grammatical function words (determiners, prepositions, auxiliary verbs). A child might say "mummy go shop" rather than "mummy is going to the shop." The analogy with a telegram is apt: the essential content words are present, but the grammatical "glue" is missing.

Post-telegraphic stage (36 months onwards)

Children begin producing utterances that increasingly resemble adult grammar. Function words appear, sentence structures become more complex, and subordinate clauses start to emerge. By the age of five, most children can produce grammatically complete sentences in a range of structures, although development continues well into the school years.

Phonological Development

Young children's pronunciation differs from adult speech in systematic ways. When analysing transcript data, you should be able to identify specific simplification processes:

Deletion -- omitting sounds, particularly at the ends of words or in unstressed syllables. "Cat" might become "ca"; "banana" might become "nana."
Substitution -- replacing one sound with another that is easier to produce. A common example is fronting, where sounds made at the back of the mouth (like /k/) are replaced with sounds made at the front (like /t/), so "cat" becomes "tat."
Cluster reduction -- simplifying consonant clusters. "Spoon" becomes "poon"; "tree" becomes "tee."
Addition -- adding extra sounds, often an unstressed vowel. "Dog" might become "doggy" (though this also has a diminutive/affectionate function).

These processes are not random errors -- they reflect the child's developing motor control and phonological system. Most simplification processes resolve naturally between the ages of three and six.

Lexical and Semantic Development

First words typically appear around 12 months and tend to name important people, objects, and actions in the child's immediate environment -- "mummy," "ball," "no," "more."

Two important concepts for the exam:

Overextension -- using a word too broadly. A child might call all four-legged animals "dog" or use "daddy" to refer to any adult male. Eve Clark distinguished between categorical overextension (based on shared features) and analogical overextension (based on perceived similarity of shape or function).
Underextension -- using a word too narrowly. A child might use "car" only for the family car, not recognising that the word applies to all cars.

Vocabulary growth accelerates dramatically around 18--24 months, a phenomenon sometimes called the vocabulary spurt or naming explosion. By the age of two, a child may have a productive vocabulary of around 200--300 words, and by five, several thousand.

Grammatical Development

Grammatical development is one of the richest areas for exam analysis.

Word order -- English-speaking children typically grasp basic subject-verb-object word order early. Even at the two-word stage, "mummy drink" is far more common than "drink mummy," suggesting an innate or early-acquired sense of syntactic structure.

Inflectional morphology -- children begin adding grammatical morphemes (such as the plural -s, the possessive -'s, the past tense -ed, and the progressive -ing) during the telegraphic and post-telegraphic stages. A crucial concept here is overgeneralisation (also called virtuous errors). When a child says "goed" instead of "went," "mouses" instead of "mice," or "runned" instead of "ran," they are demonstrating that they have internalised a grammatical rule and are applying it consistently -- even to irregular forms. This is strong evidence against a purely imitative model of language acquisition, because children produce forms they have never heard an adult say.

Question formation develops in stages: children initially signal questions through rising intonation alone ("daddy gone?"), then begin using question words at the start of utterances ("where mummy go?"), and finally acquire subject-auxiliary inversion ("where is mummy going?").

Negation follows a similar path: external negation ("no want it"), then internal negation placed before the verb ("I no like it"), and finally correct auxiliary + negation ("I don't like it").

Pragmatic Development

Pragmatics -- the social rules of language use -- is sometimes overlooked in revision, but it matters.

Turn-taking -- even very young babies engage in proto-conversations with caregivers, with alternating vocalisations and silences. Children gradually learn to wait for their turn, respond relevantly, and manage conversational repair when misunderstandings occur.
Politeness -- children learn politeness conventions (saying "please" and "thank you") partly through explicit instruction and partly through observation. More sophisticated aspects of politeness, such as indirect requests ("could you pass the salt?"), develop later.
Conversational skills -- topic maintenance, the ability to adapt language for different audiences, and understanding of non-literal language (irony, sarcasm, idiom) all develop through childhood and into adolescence.

Key Theories of Language Acquisition

You will be expected to evaluate theoretical perspectives in your essay. The main positions are:

B.F. Skinner -- Behaviourist/Imitation Theory

Skinner argued that language is acquired through operant conditioning: children imitate the language they hear, and correct usage is reinforced through positive feedback (praise, successful communication) while incorrect usage is corrected or ignored. This theory accounts for the role of the environment and explains why children learn the specific language of their community. However, it struggles to explain overgeneralisation errors (children produce forms they have never heard), the speed of acquisition, and the creativity of children's language.

Noam Chomsky -- Nativist Theory and the Language Acquisition Device (LAD)

Chomsky proposed that humans are born with an innate capacity for language -- a Language Acquisition Device (LAD) -- which contains knowledge of universal grammatical principles common to all human languages. This explains why children across cultures pass through similar stages at similar ages, why they acquire language so rapidly despite receiving imperfect input (the "poverty of the stimulus" argument), and why they produce overgeneralised forms that demonstrate rule-learning rather than imitation. Critics argue that the theory underestimates the role of social interaction and input.

Jerome Bruner -- Interactionist Theory and the Language Acquisition Support System (LASS)

Bruner proposed the LASS as a complement to Chomsky's LAD. He argued that caregivers actively support language development through routines, scaffolding, and interactive formats (such as reading books together or playing peek-a-boo). Child-directed speech (CDS) -- the simplified, exaggerated, and repetitive speech that adults typically use with young children -- plays a central role in this model.

Jean Piaget -- Cognitive Theory

Piaget argued that language development is tied to cognitive development. Children can only express concepts they have already understood. For example, a child must have grasped the concept of object permanence before they can meaningfully talk about absent objects. Language, in this view, follows thought rather than driving it.

Lev Vygotsky -- Zone of Proximal Development (ZPD)

Vygotsky emphasised the role of social interaction in cognitive and linguistic development. The ZPD describes the gap between what a child can do alone and what they can do with the support of a more knowledgeable other (a parent, teacher, or older child). Language development occurs most effectively within this zone, where scaffolded interaction pushes the child just beyond their current level.

Literacy Development

The exam may also ask about how children develop reading and writing skills.

Chall's stages of reading development provide a useful framework:

Stage 0 (pre-reading) -- children develop awareness of print, recognise some letters and familiar words (such as their own name), and understand that text carries meaning.
Stage 1 (initial reading/decoding) -- children learn letter-sound correspondences and begin decoding unfamiliar words.
Stage 2 (confirmation and fluency) -- reading becomes more fluent and children consolidate their decoding skills through practice.
Stage 3 (reading for learning) -- children begin using reading as a tool for acquiring new information.
Stages 4 and 5 -- increasingly sophisticated and critical reading.

Kroll's stages of writing development describe how children's writing matures:

Preparatory stage -- basic motor skills, learning to form letters.
Consolidation stage -- writing resembles spoken language, with simple sentence structures and informal features.
Differentiation stage -- children begin to distinguish between spoken and written registers, using more complex grammar and formal conventions.
Integration stage -- the writer can move confidently between different styles and registers, adapting their writing to purpose and audience.

Rothery's categories of children's writing identify common types of early writing: observation/comment, recount, report, and narrative. These categories are useful for analysing the kinds of texts children produce at different stages.

Using Data in Child Language Essays

In the exam, you may be given a transcript of a child's speech. When analysing it:

Identify the stage of development the child appears to be at, supporting your judgement with specific examples from the data.
Apply linguistic frameworks systematically: look at phonology, lexis, grammar, and pragmatics in turn.
Use relevant terminology precisely -- do not simply describe what the child is doing; name the linguistic features and processes.
Connect your observations to theory -- does the data support or challenge the views of Skinner, Chomsky, Bruner, Piaget, or Vygotsky?
Avoid sweeping generalisations. The best answers acknowledge that development varies between children and that a single transcript provides a snapshot, not a complete picture.

Part Two: Language Change (Paper 2, Section A Option)

How and Why Language Changes

Language is not static. English has changed continuously over more than a thousand years, and it continues to change today. Language change operates at every level -- lexis, grammar, phonology, and orthography -- and is driven by social, technological, cultural, and political forces.

A Brief Historical Overview

Old English (c. 450--1100) -- a highly inflected, Germanic language. Texts such as Beowulf are largely unintelligible to modern English speakers without specialist training.
Middle English (c. 1100--1500) -- following the Norman Conquest, English absorbed thousands of French and Latin loan words. Inflections were gradually lost, and word order became more important for conveying grammatical meaning. Chaucer's Canterbury Tales is the most famous Middle English text.
Early Modern English (c. 1500--1700) -- the language of Shakespeare and the King James Bible. The Great Vowel Shift changed the pronunciation of long vowels, and the introduction of the printing press (by William Caxton in 1476) began the process of standardising spelling. This period also saw significant borrowing from Latin, Greek, and other languages.
Modern English (c. 1700--present) -- characterised by increasing standardisation (aided by dictionaries such as Samuel Johnson's in 1755), global spread through colonialism and trade, and rapid lexical expansion driven by industrialisation, science, and technology.

Lexical Change

Lexical change is the most visible form of language change and offers rich material for essays.

Neologisms -- entirely new words. These can be coined for new inventions, concepts, or cultural phenomena ("selfie," "blog," "podcast").
Borrowing/loan words -- words adopted from other languages. English has borrowed extensively from French ("beef," "justice," "parliament"), Latin ("education," "virus"), Hindi ("jungle," "shampoo"), Arabic ("algebra," "cotton"), and many other languages.
Semantic change -- shifts in a word's meaning over time:
- Broadening (generalisation) -- a word's meaning becomes wider. "Bird" originally meant a young bird specifically; now it refers to all birds.
- Narrowing (specialisation) -- a word's meaning becomes more restricted. "Meat" once meant food in general; now it refers specifically to animal flesh.
- Amelioration -- a word's connotations become more positive. "Knight" originally meant a boy or servant; it now carries connotations of honour and nobility.
- Pejoration -- a word's connotations become more negative. "Villain" originally meant a farm worker; it now means an evil person.
Archaic words -- words that fall out of common use ("thou," "hither," "forsooth").
Word formation processes: compounding (combining existing words -- "laptop," "football"), blending (merging parts of words -- "brunch" from breakfast and lunch, "smog" from smoke and fog), clipping (shortening words -- "phone" from telephone, "exam" from examination), acronyms (words formed from initial letters -- "scuba," "radar"), and eponyms (words derived from proper names -- "sandwich," "boycott," "pasteurise").

Grammatical Change

English grammar has changed profoundly since the Old English period.

Loss of inflections -- Old English relied heavily on inflectional endings to signal grammatical relationships (case, gender, number). Most of these inflections were lost during the Middle English period, making word order increasingly important.
Standardisation -- the establishment of standard grammatical conventions, aided by printing, education, and prescriptive grammars. Constructions that were once acceptable (such as double negatives for emphasis) became stigmatised.
Changes in word order -- Old English had relatively flexible word order because inflections carried grammatical information. As inflections disappeared, English settled into a more rigid subject-verb-object order.
Changes in verb forms -- the progressive aspect ("I am going") became more common from the Early Modern period onwards. The use of "do" as an auxiliary in questions and negatives ("do you know?" rather than "know you?") also developed during this period.

Phonological Change

Pronunciation changes constantly, though it is less visible in writing.

The Great Vowel Shift (roughly 1400--1700) -- a major systematic change in the pronunciation of long vowels. Words like "name," "time," and "house" were originally pronounced with their continental vowel values (roughly "nah-meh," "tee-meh," "hoos"). The shift is one reason why English spelling often seems inconsistent with pronunciation.
Ongoing pronunciation changes -- these continue today. Features such as th-fronting (pronouncing "think" as "fink"), the spread of glottal stops, and changes in vowel quality across different dialects are all examples of phonological change in progress.

Orthographic Change

Spelling in English was highly variable before the invention of printing.

Caxton and the printing press -- William Caxton set up the first English printing press in 1476. Printing encouraged standardisation because it fixed spellings in widely distributed texts. However, Caxton's decisions sometimes preserved older pronunciations (such as the silent "k" in "knight" and the "gh" in "night").
Johnson's dictionary (1755) -- Samuel Johnson's A Dictionary of the English Language was a landmark in standardising English spelling. While Johnson sometimes chose spellings based on etymology rather than pronunciation, his dictionary provided an authoritative reference that helped reduce variation.

Causes of Language Change

You should be able to discuss the forces that drive change:

Technology -- new inventions and technologies require new words and reshape communication (the printing press, the telephone, the internet, social media).
Social change -- shifts in social attitudes, including changing views on gender, class, and identity, influence language. Attempts to make language more inclusive (such as the use of "they" as a singular pronoun) are examples of socially motivated change.
Contact with other languages -- trade, invasion, colonialism, immigration, and globalisation all bring languages into contact and result in borrowing.
Cultural shifts -- changes in fashion, entertainment, music, and popular culture generate new vocabulary and new ways of using language.

Key Theorists and Perspectives

Jean Aitchison -- Metaphors for Attitudes to Language Change

Aitchison identified three common metaphors that people use when discussing language change, all of which she critiqued:

The damp spoon metaphor -- the idea that language change is caused by laziness (like leaving a damp spoon in the sugar bowl). Aitchison rejected this, arguing that language change often involves complex restructuring, not simplification through carelessness.
The crumbling castle metaphor -- the idea that English was once a perfect, complete structure that is now decaying. Aitchison pointed out that language has never been static and there is no golden age to return to.
The infectious disease metaphor -- the idea that language change spreads like a contagion and should be resisted. Aitchison argued that change is natural, inevitable, and often functional.

Prescriptivism vs Descriptivism

This is a central debate in language change essays:

Prescriptivists believe that there are correct and incorrect forms of language and that standards should be maintained. They tend to view change as decline.
Descriptivists believe that linguists should describe how language is actually used rather than prescribing how it should be used. They tend to view change as natural and value-neutral.

In your essay, you should demonstrate awareness of both perspectives and show that you can evaluate them critically. The strongest answers avoid simply taking sides and instead explore the tension between the two positions with reference to specific examples.

How to Approach the Paper 2 Language Change Essay

The Paper 2 Section A question will typically present a statement or viewpoint about language change and ask you to evaluate it. To score highly:

Plan before you write. Identify the key terms in the question and decide which areas of language change are most relevant (lexical, grammatical, phonological, orthographic).
Use specific examples. Vague references to "language changing over time" will not score well. Name specific words, constructions, or historical developments.
Engage with theory. Reference Aitchison's metaphors and the prescriptivist/descriptivist debate where relevant. Show that you understand different perspectives on change.
Cover multiple language levels. The best answers discuss change at the level of lexis, grammar, phonology, and/or orthography rather than focusing on just one.
Write analytically, not narratively. Do not simply tell the story of English from Old English to the present. Use your historical knowledge to support analytical points about how and why change occurs.
Address the question directly. Every paragraph should connect back to the specific statement or question you have been given.
