Consonants are speech sounds produced with some degree of obstruction or constriction in the vocal tract. Unlike vowels, where air flows freely, consonants involve the articulators (tongue, lips, teeth, palate, vocal folds) coming close together or making contact to modify the airstream. English has 24 consonant phonemes, and the system is impressively orderly: every one can be pinned down by a three-term label. For AQA A-Level English Language (7702), this precision is exactly what earns AO1 credit, and the consonant features that vary between accents — TH-fronting, H-dropping, glottalisation, L-vocalisation — are among the most productive things to analyse in spoken data, feeding AO3 when you link them to region, class and identity. As elsewhere, the reference accent here is RP / Standard Southern British English (SSBE), used as a documented baseline, not a standard of correctness.
Every consonant is described by three parameters: voicing, place of articulation and manner of articulation. Together these uniquely identify each sound, and the convention is to give them in the order voicing–place–manner: /b/ is a "voiced bilabial plosive"; /ʃ/ is a "voiceless post-alveolar fricative". Getting all three terms right, in order, is the single clearest way to show secure phonological method.
Voicing refers to whether the vocal folds (vocal cords) in the larynx vibrate during the sound. You can test it: place your fingers on your throat and produce a long /zzz/ (you feel buzzing — voiced) then a long /sss/ (no buzzing — voiceless).
| Type | Description | English sounds |
|---|---|---|
| Voiceless (unvoiced) | Vocal folds apart, no vibration | /p/, /t/, /k/, /f/, /θ/, /s/, /ʃ/, /tʃ/, /h/ |
| Voiced | Vocal folds together, vibrating | /b/, /d/, /g/, /v/, /ð/, /z/, /ʒ/, /dʒ/, /m/, /n/, /ŋ/, /l/, /r/, /j/, /w/ |
Many English consonants come in voicing pairs — identical in place and manner, differing only in voicing. These pairs (often called fortis–lenis) are the backbone of the obstruent system:
| Voiceless | Voiced | Place | Manner |
|---|---|---|---|
| /p/ (pat) | /b/ (bat) | bilabial | plosive |
| /t/ (tin) | /d/ (din) | alveolar | plosive |
| /k/ (cap) | /g/ (gap) | velar | plosive |
| /f/ (fan) | /v/ (van) | labiodental | fricative |
| /θ/ (thin) | /ð/ (then) | dental | fricative |
| /s/ (sue) | /z/ (zoo) | alveolar | fricative |
| /ʃ/ (ship) | /ʒ/ (measure) | post-alveolar | fricative |
| /tʃ/ (church) | /dʒ/ (judge) | post-alveolar | affricate |
The sonorants /m/, /n/, /ŋ/, /l/, /r/, /j/, /w/ are all voiced and have no voiceless partner in English; /h/ is voiceless and has no voiced partner. Voicing is rarely "all or nothing" in real speech — voiced obstruents are often only partly voiced at the edges of an utterance — but for A-Level the phonemic voiced/voiceless distinction is what matters.
Key Definition: Voicing — vibration of the vocal folds during a speech sound. Sounds with vibration are voiced; sounds without are voiceless.
Place of articulation describes where the obstruction is made. Moving from the lips back to the glottis:
| Place | Articulators involved | English sounds | Example words |
|---|---|---|---|
| Bilabial | Both lips together | /p/, /b/, /m/, /w/ | pat, bat, mat, wet |
| Labiodental | Lower lip to upper teeth | /f/, /v/ | fat, vat |
| Dental | Tongue tip at/against upper teeth | /θ/, /ð/ | think, this |
| Alveolar | Tongue tip/blade at the alveolar ridge (the bony ridge behind the upper teeth) | /t/, /d/, /n/, /s/, /z/, /l/ | tip, dip, nip, sip, zip, lip |
| Post-alveolar | Tongue blade just behind the alveolar ridge | /ʃ/, /ʒ/, /tʃ/, /dʒ/, /r/ | ship, measure, chip, jam, rip |
| Palatal | Front of tongue to the hard palate | /j/ | yes |
| Velar | Back of tongue to the soft palate (velum) | /k/, /g/, /ŋ/ | kit, get, sing |
| Glottal | Constriction at the glottis (between the vocal folds) | /h/, [ʔ] | hat; glottal stop in "butter" [bʌʔə] |
The glottal stop [ʔ] is not a separate phoneme of RP (it does not, by itself, distinguish word meanings), but it is an extremely common allophone of /t/ in many British accents and a high-frequency feature in spoken data. /w/ has a dual place — bilabial and velar at once — hence "labial-velar".
Key Definition: Place of articulation — the location in the vocal tract where the primary constriction or obstruction occurs in producing a consonant.
Manner of articulation describes how the airstream is modified. The English manners are plosive, fricative, affricate, nasal, approximant and lateral.
Plosives completely block the airstream, build up pressure behind the closure, then release it in a burst. English has six: /p, b/ (bilabial), /t, d/ (alveolar), /k, g/ (velar). They pass through three phases — the approach (articulators close), the hold/compression (closure complete, pressure builds) and the release (burst). At the start of a stressed syllable the voiceless plosives are aspirated ([pʰ, tʰ, kʰ], as in "pin" [pʰɪn]) but not after /s/ ("spin" [spɪn]) — a classic allophonic alternation.
Fricatives narrow the vocal tract so the airstream is forced through a small gap, creating audible turbulence (friction). English has nine: /f, v/ (labiodental); /θ, ð/ (dental); /s, z/ (alveolar); /ʃ, ʒ/ (post-alveolar); /h/ (glottal). They can be sustained for as long as the breath lasts. The sibilants /s, z, ʃ, ʒ/ are especially intense, high-pitched fricatives made with a grooved tongue that channels the airstream onto the teeth — important later for plosive vs sibilant patterning in stylistic analysis.
Affricates begin like a plosive (complete closure) and end like a fricative (slow, friction-filled release). English has two, both post-alveolar: /tʃ/ (chip) and /dʒ/ (judge). They behave as single phonemes even though each is transcribed with two symbols — /tʃ/ is not the cluster /t/+/ʃ/ but a single unit, which is why "church" /tʃɜːtʃ/ has one affricate at each end, not a plosive followed by a fricative.
Nasals lower the velum so air escapes through the nose while the mouth is blocked at some point. English has three: /m/ (bilabial), /n/ (alveolar), /ŋ/ (velar). /ŋ/ has a restricted distribution — it never begins an English word and only ever follows a vowel, spelled "ng" or "n" before /k/ or /g/ (as in "think" /θɪŋk/). The variable pronunciation of the "-ing" suffix as /ɪŋ/ or /ɪn/ ("walking" vs "walkin'") is one of the most-studied sociolinguistic variables in English and a reliable point to analyse.
Approximants bring articulators close without creating turbulence; the airflow stays smooth, so they are vowel-like acoustically. English has /r/ (post-alveolar), /j/ (palatal) and /w/ (labial-velar). /j/ and /w/ are often called semivowels or glides because they pattern as consonants but are phonetically vowel-like (/j/ resembles /iː/, /w/ resembles /uː/).
The lateral approximant /l/ is made with the tongue tip on the alveolar ridge while air flows around the sides of the tongue. English has one lateral, /l/ ("lot", "pill"), with two key allophones: clear [l] before vowels ("light") and dark/velarised [ɫ] after vowels or before consonants ("full", "milk"). In Cockney and Estuary English, dark /l/ is often vocalised to a vowel-like [ʊ] or [o], so "milk" becomes [mɪʊk] — a spreading change worth flagging as AO3 evidence.
Key Definition: Manner of articulation — how the airstream is modified in producing a consonant, including the degree and type of obstruction. English manners: plosive, fricative, affricate, nasal, approximant, lateral.
The complete chart arranges all 24 phonemes by place (columns) and manner (rows); within a cell the voiceless sound is on the left, the voiced on the right. Reading it fluently lets you generate any sound's three-term label on demand.
| Manner | Bilabial | Labiodental | Dental | Alveolar | Post-alveolar | Palatal | Velar | Glottal |
|---|---|---|---|---|---|---|---|---|
| Plosive | p · b | t · d | k · g | |||||
| Nasal | m | n | ŋ | |||||
| Fricative | f · v | θ · ð | s · z | ʃ · ʒ | h | |||
| Affricate | tʃ · dʒ | |||||||
| Approximant | w | r | j | (w) | ||||
| Lateral | l |
To name a sound, read down to its row (manner) and across to its column (place), then add voicing: the cell at Fricative × Post-alveolar holds /ʃ/ and /ʒ/, so /ʒ/ is the "voiced post-alveolar fricative".
Beyond the individual labels, consonants fall into natural classes — groups that share features and pattern together in phonological rules. The most important top-level division is between obstruents and sonorants.
Why does this matter? Because phonological generalisations are stated over natural classes, not random lists. The English plural and past-tense rules, for instance, refer to the class of voiceless obstruents (which take /s/ and /t/) versus voiced sounds (which take /z/ and /d/). When you can say "the suffix assimilates in voicing to the preceding obstruent", you are using the class concept that makes the rule general — a clear sign of phonological maturity.
Key Definition: Natural class — a set of sounds sharing one or more distinctive features and patterning together in phonological rules. Obstruents (plosives, fricatives, affricates) involve major airflow obstruction; sonorants (nasals, approximants, lateral, vowels) involve open, usually voiced airflow.
While vowels carry the bulk of accent variation, a cluster of consonant variables is regularly tested in spoken data because each is salient and socially loaded. You should be able to name, transcribe and contextualise each.
| Variable | What changes | Example | Typical social/regional indexing |
|---|---|---|---|
| Rhoticity | Whether post-vocalic /r/ is pronounced | "car" /kɑː/ (non-rhotic) vs /kɑːr/ (rhotic) | Non-rhotic: RP, most of England; rhotic: Scotland, Ireland, the West Country, most of the US |
| Glottal replacement | /t/ → [ʔ] | "butter" [bʌʔə] | Spread from Cockney via Estuary English; now near-universal informally |
| H-dropping | /h/ deleted in stressed lexical words | "house" → [aʊs] | Most urban English accents; absent from RP, Scottish, Irish, Geordie; heavily stigmatised |
| TH-fronting | /θ ð/ → /f v/ | "three" /friː/, "brother" /ˈbrʌvə/ | London origin, spreading nationally among young speakers (dialect levelling) |
| L-vocalisation | dark [ɫ] → [ʊ]/[o] | "milk" [mɪʊk] | Cockney/Estuary, spreading |
| Yod-coalescence | /tj dj/ → /tʃ dʒ/ | "Tuesday" /ˈtʃuːzdeɪ/ | Increasingly standard; now lexicalised for many |
Two analytical reminders. First, describe each featurally (TH-fronting changes only place; glottalling changes manner and place, replacing an oral plosive with a glottal stop). Second, separate the linguistic description from the social evaluation: H-dropping is "stigmatised" as a social fact about listener attitudes, not as a linguistic defect — the unsplit, h-dropping pattern is every bit as rule-governed as RP.
Consonants are a major resource in literary and rhetorical texts, and naming their effects precisely (with IPA, not spelling) is valuable in Paper 1.
As with assonance, these effects are phonaesthetic tendencies, not fixed meanings: the disciplined approach is to identify the repeated sounds by their phonetic class and argue for their effect in context, rather than claiming that, say, sibilance "always" signals something sinister.
A transcript of a teenage Estuary English speaker reads: "I thought I'd get a little water bottle."
