Consonance is the repetition of identical or similar consonant sounds in words that are close to each other, usually within the same line or sentence. Unlike alliteration, which only repeats the opening consonant, consonance picks up the same sound anywhere within or at the end of words.
What is the difference between consonance, alliteration, and assonance?
These three sound devices are closely related but distinct. Knowing the difference helps you be precise in your analysis:
| Device | Where the sound repeats | Example | Repeated sound |
|---|---|---|---|
| Alliteration | At the start of words | "Silver snakes slid" | /s/ — opening consonants |
| Consonance | Anywhere in words (middle or end) | "black trick" | /k/ — within and at ends |
| Assonance | Vowel sounds within words | "the easy eagle" | /iː/ — internal vowels |
In practice, a single line of poetry may use all three at once. The key is to identify which sounds are repeated and where in the words they appear. If the repeated consonant is only at the start of each word, that is alliteration. If it appears in the middle or end — or in a mix of positions — that is consonance.
What sounds are most commonly used in consonance?
Different consonants carry different sonic associations that poets exploit:
- Plosive consonants (b, d, g, k, p, t) create a harsh, sharp, or percussive effect — useful for violence, anger, or sudden action.
- Fricative consonants (f, v, s, sh, th, z) create a soft, hissing, or breathy effect — useful for whispers, wind, secrecy, or unease.
- Lateral and nasal consonants (l, m, n, r) create smooth, flowing, or gentle effects — useful for calm, tenderness, or sadness.
- Sibilant consonants (s, sh, z) create a particular form of consonance sometimes called sibilance, which has its own specific entry in most exam mark schemes and is worth naming separately when it appears.
Worked examples in poetry
Example 1 — harsh plosives, Wilfred Owen:
"The blocking wheels stick; gagged guts; guttering, rotting, dying."
The repeated /k/ and /t/ sounds land like physical blows — they are hard to speak and difficult to swallow. Owen uses this consonance to make the reader experience the ugliness of death physically, not just intellectually. The sounds enact the choked, halting nature of the event.
Example 2 — soft fricatives, John Keats, To Autumn:
"Season of mists and mellow fruitfulness"
The repeated /f/ and /s/ sounds are gentle and whispering. Keats uses this consonance to give the line a slow, languid quality that mirrors the drowsy, ripe mood of autumn itself. The sound texture matches — and reinforces — the meaning.
In both examples, the analytical move is the same: identify the repeated consonant, describe its sonic quality, and then link that quality to the poem's mood, theme, or subject.
How do I write analytically about consonance?
The most common mistake is identifying consonance without analysing its effect. Simply writing "the poet uses consonance" earns no marks at GCSE — you must connect the sound to the meaning:
Basic (insufficient): "The poet uses consonance with the /k/ sound."
Analytical (rewarded): "The repeated /k/ sound in 'black rocks cracked' creates a harsh, percussive effect that mirrors the violence of the scene, making the reader feel the impact physically rather than simply reading about it."
Notice the structure: name the device → identify the specific sound → describe its sonic quality → link to effect on the reader or meaning of the text.
Is consonance the same as rhyme?
Not quite, but they are related. Rhyme typically involves the repetition of both vowel and consonant sounds from the stressed syllable onwards ("cat / hat", "dream / stream"). Consonance repeats only consonant sounds, so the vowels may be entirely different ("struck / track", "lit / late", "black / brick"). When consonance appears at the ends of lines in place of full rhyme, it is often called half rhyme or slant rhyme — a technique used to create an unsettled, incomplete feeling, since the ear expects a full rhyme but receives only a partial match.
Wilfred Owen uses half rhyme extensively in his war poetry ("groaned / ground", "nervous / knife") to create unease — the near-miss of the sound mirrors the randomness and incompleteness of the soldiers' deaths.
Frequently asked questions
Do I need to identify consonance specifically, or can I just say "sound effects"?
In a KS3 task, "sound effects" or "repetition of consonant sounds" may receive credit, but in GCSE analysis, naming the device precisely — consonance, or sibilance if it involves /s/, /sh/, /z/ sounds — demonstrates a higher level of technical vocabulary. Examiners reward precise terminology, but only when it is followed by a genuine analysis of effect; precise naming without analysis still earns low marks.
Can consonance appear in prose as well as poetry?
Yes. Skilled prose writers use consonance for rhythm and effect in exactly the same way as poets — it is simply less obvious because there is no line structure to make sound devices stand out. In exam texts for GCSE English Language, you may be asked to analyse consonance (or sibilance) in a fiction or non-fiction extract. The analytical approach is identical: identify → name → explain the sonic quality → link to meaning or effect.
What if the consonant sounds are similar but not identical?
Consonance traditionally involves the repetition of the same consonant sound (not necessarily the same letter — "king" and "click" share the /k/ sound even though one is spelled with k and one with ck). Similar but not identical sounds — for instance, /d/ and /t/ (voiced and unvoiced equivalents) — are sometimes called near-consonance and can still be analysed for effect, especially in poetry, though it is safer to describe what you hear rather than force a technical term onto an approximate match.
How is consonance different from sibilance?
Sibilance is a subset of consonance: it refers specifically to the repetition of hissing or hushing sounds (/s/, /sh/, /z/). Because sibilance is so commonly tested in GCSE poetry analysis, it has its own recognised name. If the repeated consonants are /s/ sounds, call it sibilance and explain its whispering, hissing, or menacing effect. If the repeated consonants are something else — /k/, /t/, /l/ — use the broader term consonance.
