wavelet singular

Morphology

wavelet = wave (semi-transparent) = wave + let

Formed from 'wave' + diminutive '-let' but used as a technical term for a class of functions, so the relation to 'small wave' is metaphorical and specialized.

Etymology

Wavelet comes from wave plus the ending -let meaning 'small', just like booklet; in math a wavelet is a 'small wave' shape used to analyze signals or data at different sizes, so the name shows it is a little wave that helps study information.
