What a lovely word!
All writers have a natural instinct for using and appreciating assonance. It means to create a resemblance of sound in a phrase by repeating the same or similar vowel sounds.
Sometimes I imagine that language was birthed through assonance—that exquisite, subtle combination of sound and meaning. The dawn of language must have been punctuated by a grunt of love or whisper of fear or murmur of contentment.
