frizz

The word 'frizz' is believed to be an onomatopoeic formation from the late 16th century, imitating the sound or visual effect of something sizzling or crackling. This sound symbolism was then applied to describe the action of curling hair, evoking the image and perhaps even the faint sound of hair being tightly curled or crinkled. Over time, its meaning specialized to refer almost exclusively to hair forming into a mass of small, tight curls, moving from a general expressive verb to a specific descriptive term in hairstyling.

The word is a simplex, likely of imitative or expressive origin, and cannot be meaningfully segmented into distinct morphemes within its modern English spelling.
