What does assonant mean?
'Assonant' describes language that features assonance — the deliberate or noticeable repetition of the same or similar vowel sounds across nearby words, most often in poetry, song lyrics, and literary prose. A phrase such as 'the rain in Spain' is assonant because of its recurring long 'a' sound. The word functions almost exclusively as an adjective and appears chiefly in contexts concerned with poetics, rhetoric, phonetics, and translation, where writers analyze how sound shapes meaning and mood. Its connotations are technical and appreciative rather than judgmental: calling a passage assonant highlights its musicality and echo effects without implying anything about its content. Related terms include the noun 'assonance', from which it derives, and the contrasting term 'consonant', which concerns repeated consonant sounds instead of vowels. For students of literature and for anyone interested in why certain lines feel pleasingly rhythmic even without rhyme, 'assonant' offers a precise way to name that effect.
Characterized by or exhibiting assonance; containing repeated identical or similar vowel sounds in neighboring words.
"The poem's assonant lines, thick with murmuring 'u' and 'o' sounds, create a low, humming music."
Used almost entirely in literary criticism, linguistics, and discussions of poetry or translation.
(Rare, now chiefly historical) A word or sound that corresponds to another in vowel sound.
This noun sense is largely obsolete; modern usage strongly favors the adjective.
Swap one letter and you flip the meaning: 'assonant' repeats vowels, its near-twin 'dissonant' names harsh, clashing sounds — both born from the same Latin verb for 'to sound'.

Etymology of assonant
'Assonant' comes from the Latin verb 'sonare', meaning 'to sound', combined with the prefix 'ad-' (here assimilated to 'as-'), conveying correspondence or response in sound. It entered English in the early 17th century alongside the related noun 'assonance', which had been borrowed slightly earlier from French. The same Latin root gives English a whole family of sound-related words, including 'sonorous', 'sonic', 'resonate', and — with a different prefix — 'dissonant' and 'consonant'.
