Word classes (also called parts of speech) are the fundamental categories into which words are grouped according to their grammatical behaviour. At A-Level this is foundational terminology rather than an end in itself: AQA 7702 treats grammar as a method of language analysis integrated into every component — Paper 1, Paper 2 and the Non-Examination Assessment (NEA) — and the primary assessment objective served by accurate labelling is AO1 (applying appropriate methods and terminology). The fuller objective grid is AO1 26 · AO2 26 · AO3 23 · AO4 15 · AO5 10, so naming a word class is the entry ticket; the marks accumulate when you move from labelling to analysing the effect of a word-class choice in an authentic text. A genuinely strong response, in the language of the band descriptors, will identify a feature, classify it correctly, and then explore why that choice matters for meaning, audience or representation.
Grammarians divide the classes in two. Open classes (nouns, verbs, adjectives, adverbs) readily accept new members — every year English coins new nouns (influencer, staycation) and verbs (to doomscroll) — which is why they are sometimes called lexical classes; they carry the bulk of a text's content. Closed classes (pronouns, prepositions, determiners, conjunctions, auxiliary and modal verbs, and interjections) have a small, fixed membership that changes only over centuries; these are the grammatical or function words that hold the structure together. The descriptive reference grammar this lesson leans on is Quirk, Greenbaum, Leech and Svartvik's A Comprehensive Grammar of the English Language (1985), which remains the standard taxonomy underpinning A-Level mark schemes.
A word of method before the categories themselves: class is determined by function in a particular sentence, not by the word in isolation. The same orthographic form can belong to several classes, so you must always test a word against the slot it fills.
Nouns denote entities — people, places, things, concepts and qualities. The reliable structural tests are that a noun can head a noun phrase, can usually be preceded by a determiner (the table, a decision), and can typically be made plural or possessive (tables, the table's leg). Nouns sub-classify along several overlapping dimensions:
Key Definition: Nominalisation — converting a verb or adjective into a noun (destroy → destruction; fail → failure; poor → poverty; decide → decision). Nominalisation is a hallmark of formal, academic and bureaucratic registers because it repackages a process as a thing. Crucially, it lets a writer delete the agent: "the destruction of the forest" tells us something was destroyed but quietly removes whoever did it. This is a prime target for analysis under AO3 (contextual factors) when examining how institutional texts manage responsibility.
Verbs denote actions, processes, states and events, and they are the one obligatory element of a finite clause — without a verb you have a phrase or a minor sentence, not a full clause. The structural tests are that a lexical verb inflects for tense (walk / walked), takes the third-person singular -s (she walks), and forms participles (walking, walked). Several sub-classifications matter:
Key Definition: Transitivity — the relationship between a verb and the elements it requires. A transitive verb takes a direct object (she read the book); an intransitive verb takes none (he slept); a ditransitive verb takes both an indirect and a direct object (she gave him the book). Some verbs are copular (linking) and take a complement rather than an object (she is a doctor). Analysing transitivity reveals who does what to whom, which makes it one of the sharpest tools for examining agency, power and representation in a text.
Adjectives modify nouns, specifying qualities, properties and characteristics. They occupy two main positions: attributive, before the noun (a tall building), and predicative, after a copular verb (the building is tall; she seemed anxious). A few adjectives are restricted to one slot — the main reason (attributive only; *the reason is main) versus the child is asleep (predicative only; *the asleep child) — which is a useful diagnostic detail.
Adverbs are the most varied open class. They modify verbs, adjectives, other adverbs, or whole clauses, answering how, when, where, how often and to what degree. Many (but far from all) are formed with the -ly suffix.
Determiners precede nouns and specify reference or quantity. They are a closed class and, unlike adjectives, do not stack freely or grade (*very the, *a the book).
Prepositions encode relationships of time (before, after, during), place (in, on, under, between), direction (to, from, towards) and abstract relations (of, for, with, about, despite). A preposition heads a prepositional phrase and is followed by a noun phrase, its complement (under the bridge). This is the bridge into the next lesson on phrase structure.
Conjunctions join words, phrases or clauses, and the type of join is grammatically and stylistically loaded:
Pronouns substitute for, or refer to, nouns and noun phrases, which makes them central both to economy (you do not have to repeat the full noun phrase) and to cohesion. Key types:
Often overlooked, interjections are a closed class of words that express emotion or a discourse reaction and stand outside the clause structure: oh, wow, ouch, ugh, hey, oops. They proliferate in spontaneous speech and in informal digital writing, where they perform affect and manage interaction.
Because class is decided by function, a single form can occupy several classes. This flexibility — productive class-changing with no change of form — is called conversion (or zero derivation):
Creative or unexpected conversion is frequently the most stylistically loaded choice in a text: when a writer verbs a noun (she tabled the motion, he was sidelined) or nominalises an adjective to name a group (the poor, the unemployed), the grammar itself becomes the meaning.
A class problem that catches even careful candidates is the multi-word verb, where a lexical verb combines with one or more particles to form a single unit of meaning. There are three sub-types, and distinguishing them depends on whether the particle behaves as an adverb, a preposition, or both:
The analytical pay-off is twofold. First, multi-word verbs are markedly more frequent in informal and spoken English, while their single-word Latinate equivalents (tolerate for put up with, surrender for give up, investigate for look into) signal a more formal, written register; a text's preference between the two is therefore a precise index of formality and audience. Second, the idiomatic, non-compositional meaning of many phrasal verbs makes them a known difficulty in second-language acquisition and a marker of native-like fluency, which is worth noting when analysing learner data.
Because the same closed-class form so often straddles the determiner and pronoun classes, it is worth fixing the distinction with a single rule and a worked table: a determiner is followed by a noun it specifies; a pronoun stands in place of a noun phrase and has no following noun. The presence or absence of that following head noun decides the class every time.
| Form | As determiner (+ noun) | As pronoun (no noun) |
|---|---|---|
| this | this book is overdue | I want this |
| her | her car is outside | I saw her |
| some | some people object | some object |
| that | that man arrived | I heard that |
Applying this test stops the most common labelling error in its tracks, and it generalises: whenever you are unsure of a closed-class word, look for the structural slot rather than reaching for a memorised list.
Identifying a class is only useful if you can say why a producer's reliance on that class shapes the text. The following summary connects each class to the kinds of effect examiners reward, and it is worth internalising as a checklist of analytical angles.
| Class | Carries | Typical analytical pay-off |
|---|---|---|
| Nouns (esp. abstract) | entities, concepts | vagueness vs concreteness; nominalisation hiding agency; ideology in naming |
| Verbs (transitivity) | actions, processes, states | who acts on whom; dynamism vs stasis; agency and power |
| Adjectives (evaluative) | qualities, judgements | stance and attitude; persuasion; representation of people/places |
| Adverbs (disjuncts) | manner, stance, logic | smuggled evaluation; certainty; text organisation |
| Pronouns (person) | reference, deixis | solidarity, address, inclusion/exclusion; cohesion |
| Modal verbs | possibility, obligation | certainty, authority, hedging (developed fully later) |
Nouns and naming. The choice of noun is never neutral: the same event can be a protest, a demonstration, a riot or an uprising, and each noun encodes a stance. Abstract nouns and nominalisations are doubly significant because, as the Key Definition above noted, they can present a contested process as a settled thing and delete the human agent behind it — "the closure of the factory" names an outcome while leaving unstated who closed it. When you find a text saturated with abstract nouns, ask whose actions have been turned into nouns, and to whose advantage.
Verbs and agency. Because the verb is the obligatory element and the carrier of transitivity, verb analysis is the most direct route to questions of power and representation. A run of dynamic, transitive verbs with a human subject foregrounds that subject as a doer; a preference for stative verbs, or for verbs with inanimate subjects, can background human responsibility. Notice, too, the difference between processes that are material (physical doing: build, destroy), mental (sensing and thinking: believe, fear) and relational (being and having: is, seems) — a useful tripartite distinction drawn from Halliday's systemic functional grammar, which treats the clause as a representation of experience.
Adjectives, adverbs and stance. Evaluative adjectives and stance adverbs (disjuncts) are where a producer's attitude leaks into the grammar. A reviewer who calls a film derivative and a politician shameless has built judgement into the modifying words; a journalist who opens with predictably or astonishingly has editorialised before the clause even begins. Tracking the density and polarity of evaluative modification is a quick, reliable way to characterise the stance of an opinion text.
Pronouns and relationships. Pronoun choice constructs the relationship between producer and audience. The shift from I to inclusive we recruits the reader into a shared position; a sudden you reaches out and implicates them; they can build an out-group ("they don't understand people like us"). Pronouns are also the workhorses of cohesion, knitting a text together by pointing back to earlier nouns — a theme developed in the cohesion lesson.
You do not need to cite theory to analyse grammar well, but two genuine, well-established frameworks are safe and useful to reference. The first is the descriptive reference tradition of Quirk, Greenbaum, Leech and Svartvik (A Comprehensive Grammar of the English Language, 1985), the source of the taxonomy of classes and clause patterns used throughout this course. The second is Halliday's Systemic Functional Grammar (SFG), which asks not just what a word's class is but what function it serves — representing experience, enacting social relationships, and organising the message. Invoke these only where they sharpen a point; never invent a named "study", a statistic or a date, since fabricated attribution is penalised and undermines the integrity of an otherwise strong answer.
Examination texts are real and varied, so it helps to know what word-class analysis typically yields in the genres AQA favours. In spontaneous speech data, watch for a high density of pronouns, primary auxiliaries, fillers and interjections, all reflecting real-time, context-dependent production; a transcript may also show non-standard or regional class behaviour (e.g. them as a demonstrative determiner in them books), which you describe rather than correct. In persuasive and advertising texts, expect a concentration of evaluative adjectives, dynamic imperative verbs, second-person pronouns and abstract experiential nouns, the open-class staples of seduction and exhortation. In informational and academic texts, the give-away is heavy nominalisation and a preponderance of nouns over verbs, producing the dense, impersonal, agent-light texture of expert writing. In literary texts, the interest often lies in marked or creative class choices — conversion, unexpected modification, the foregrounding of a particular class for effect.
A small methodological point sharpens this further: the ratio of lexical (content) words to grammatical (function) words is itself a measurable index of register, sometimes discussed as lexical density. Texts dense in open-class content words (nouns, verbs, adjectives, adverbs) tend to be informationally packed and writing-like; texts with a higher proportion of closed-class function words tend to be more speech-like and interactional. You will not normally count formally in an exam, but framing an impressionistic observation in these terms — "the passage is lexically dense, dominated by content words" — demonstrates exactly the analytic vocabulary examiners reward.
Finally, remember that grammar in AQA 7702 is never assessed in a vacuum: word-class analysis feeds the wider questions the paper asks about representation (how people, places and events are constructed), audience (how the text positions and addresses its reader) and mode (how spoken and written varieties differ). A word-class observation that connects upward to one of these larger frames is always stronger than one that stays at the level of the label. The same discipline carries into the NEA, where your own investigation must apply this terminology to data you have selected — making accurate, confident word-class analysis a genuinely portable skill across the whole specification.
A disciplined word-class analysis follows four moves. (1) Identify the feature using the structural test, not a hunch — does the word take a determiner (noun-like), inflect for tense (verb-like), grade with very (adjective-like)? (2) Classify it precisely, reaching for the sub-class where it sharpens the point (an abstract noun, a stative verb, an evaluative adjective). (3) Analyse the effect, linking the choice to meaning, tone, representation or audience positioning. (4) Connect to context — genre, purpose, mode and the relationship between producer and audience — which is where AO3 marks live. The trap to avoid is "feature-spotting": listing labels with no argument earns AO1 acknowledgement only and stalls in the lower bands.
Task: Analyse how word-class choices construct authority in this opening of a public-health leaflet: "Smoking kills. Every cigarette damages your lungs. You must protect your family."
Mid-band response: "The text uses the verb 'kills' and the verb 'damages' to show that smoking is bad. There is also the modal verb 'must' which tells the reader to do something. This makes the leaflet sound serious and like it is giving advice to the reader about smoking."
Top-band response: "The leaflet front-loads two dynamic, transitive verbs — 'kills' and 'damages' — whose subjects ('Smoking', 'Every cigarette') are themselves the harmful agents, so the grammar stages tobacco as an active assailant rather than a passive substance the reader chooses. The present-tense, timeless framing of 'kills' presents the danger as a permanent law rather than a contingent risk, lending the claim the flat finality of scientific fact. Authority then shifts onto the reader through the second-person pronoun 'you' and the high-modality deontic modal 'must', which together convert medical information into direct obligation; the possessive noun phrase 'your family' widens the stakes from the individual to dependants, recruiting guilt as a persuasive resource. The cumulative effect of these closed-class function words — pronoun and modal — is to manufacture an asymmetrical relationship in which an unnamed but institutionally certain producer instructs an addressed, responsible reader."
The Mid-band answer correctly identifies word classes (it labels verbs and a modal) and so secures AO1 recognition, but it describes effect only in the broadest terms ("sounds serious") and never analyses how the grammar produces that effect. The Top-band answer integrates accurate terminology with precise, well-selected examples and pushes every label into argument: it reads transitivity for agency, present tense for a sense of universal truth, and the pronoun–modal pairing for the construction of an unequal producer–reader relationship — exactly the move from identification to analysis of effect in context that lifts a response into the higher bands.
Task: Analyse the word-class choices in this opening line of a travel-brochure description: "Nestled in an unspoilt valley, this charming family-run guesthouse offers a genuinely peaceful retreat."
Mid-band response: "There are lots of positive adjectives like 'charming', 'unspoilt' and 'peaceful' which make the guesthouse sound attractive. The verb 'offers' suggests the guesthouse is giving something to the reader. The adjectives are used to persuade the reader to want to stay there."
Top-band response: "The line is saturated with evaluative modification working to construct desirability. The past-participle adjective 'Nestled', fronted as a non-finite modifier, personifies the guesthouse as something protectively tucked away, while the pre-modifying adjectives 'unspoilt', 'charming' and 'peaceful' are all evaluative rather than factual, encoding the writer's judgement as though it were a property of the place. 'Family-run', an attributive compound, trades on connotations of warmth and authenticity that the noun 'guesthouse' alone would not carry. The stance adverb (intensifier) 'genuinely' is the cleverest choice: by pre-emptively insisting on the sincerity of the 'peaceful retreat', it implicitly concedes that such claims are often hollow elsewhere, using a single adverb to position this property against an unstated field of less authentic competitors. The verb 'offers' is a deliberately gracious choice of transitivity — the guesthouse is the agent of a giving process, casting the establishment as generous benefactor and the reader as fortunate recipient. The abstract noun 'retreat', finally, sells not a room but an experience, converting a commercial transaction into the promise of restoration. The cumulative effect of these open-class choices — evaluative adjectives, a stance adverb, a benefactive verb and an experiential abstract noun — is the seductive, connotation-laden register that defines tourism discourse."
The Mid-band answer correctly identifies the evaluative adjectives and comments sensibly on the verb 'offers', securing AO1 and touching AO2, but it groups the adjectives generically and does not analyse any single choice in depth. The Top-band answer classifies precisely across several open classes (participial adjective, evaluative adjectives, attributive compound, stance adverb, benefactive verb, abstract noun) and reads each for a distinct persuasive effect, culminating in a claim about the register of tourism discourse. Selecting individual word-class choices and arguing the specific work each performs — rather than labelling them in bulk — is what reaches the higher bands.
Make sure you can both define and apply each of the following to a real example:
Holding this vocabulary ready, and being able to convert every label instantly into a claim about meaning, effect or context, is the foundation on which all the later grammar lessons build. The terminology is never the destination; it is the precise instrument that makes analysis of effect possible.
Exam Tip: Always classify words by their function in the specific sentence, never by appearance. The word's class is a matter of the grammatical slot it fills, so apply a structural test before you commit. And never stop at the label: examiners reward the chain identify → classify → analyse effect → link to context. Pay special attention to creative class choices — a noun used as a verb, an adjective used as a noun — because these are almost always doing deliberate stylistic or ideological work.
