Sound Symbolism
Quick answer: Sound symbolism is the idea that speech sounds carry meaning on their own, as in gl- words of light. Learn what the evidence says and how poets use it.
Sound symbolism is the idea that speech sounds carry shades of meaning in themselves, independent of any dictionary definition: that gl- suggests light in glow, gleam, and glitter, that short i feels small and quick, that deep o feels large and slow. If onomatopoeia is sound imitating noise, sound symbolism is the broader claim that sound suggests qualities, size, speed, brightness, texture, even when nothing audible is being described.
Be aware that the strength of the claim is contested. Mainstream linguistics holds that the link between sound and meaning is mostly arbitrary, yet experiments keep finding stubborn patterns, and poets have trusted those patterns for centuries regardless of what the theorists decided.
How It Works
English contains clusters of words, sometimes called phonesthemes, that share both a sound and a semantic flavour: sn- gathers nose words like sniff, snout, and snore; -ump gathers heavy rounded things like lump, clump, and rump. No rule of grammar creates these families, but speakers feel them, and a new invented word like snorf gets read as nose-related instantly.
The famous experimental result is the bouba and kiki effect: shown a rounded blob and a spiky star, people across many languages call the blob bouba and the star kiki. An original pair shows the poetic version: the moon rolled slow over the meadow feels round; the lit stick clicked and split feels sharp. Same trick, different art.
Where You Will See It
Plato's dialogue Cratylus already debated whether names fit their objects by nature or convention, so the argument is ancient. Poets have voted with their drafts ever since: Tennyson's drowsy long vowels, Hopkins's compacted consonants, and the whole practice of choosing words for mouthfeel assume that sound bends meaning. Modern marketing quietly agrees, testing product names for the sizes and speeds their vowels imply, and linguists studying ideophones in languages like Japanese and Yoruba document rich systematic sound-meaning vocabularies that English only gestures toward.
How to Use It in Your Own Poems
Treat sound symbolism as a tiebreaker and an amplifier. When two words share a meaning, let their sounds decide: a small quick fear suits flick and prick sounds, an old heavy sorrow suits long back vowels. Your reader will never consciously notice, which is precisely the value.
You can also mine phonestheme families for imagery. Freewrite every gl- or cr- word you know, and patterns of light or breakage emerge ready-made. Contest judges reading for language quality respond to this coherence even without a name for it, because the poem simply sounds like what it means.
What poets can take from this
- Use short front vowels for small quick things and long back vowels for large slow things.
- Mine phonestheme families like gl-, sn-, and -ump when drafting imagery.
- Let sound choose between synonyms once meaning is settled.
- Test invented words and names on readers; their guesses reveal the sound's suggestion.
- Hold the theory lightly: sound suggests, it does not dictate, and context can override it.
Try it yourself
Invent three names for an imaginary village, one that sounds welcoming, one that sounds dangerous, and one that sounds abandoned, then write a short poem about the village whose name unsettles you most.
Questions
Is sound symbolism scientifically real?
Partly. Linguists agree most word-sound pairings are arbitrary, but robust effects like bouba and kiki, and phonestheme clusters such as gl- light words, show sound and meaning are not fully independent. The safest summary: real but limited.
How is sound symbolism different from onomatopoeia?
Onomatopoeia imitates actual sounds, as crash imitates a collision. Sound symbolism suggests non-auditory qualities, size, shape, speed, or brightness, through sound alone, as kiki suggests spikiness without any noise being described.
