the word 'sprightly' is a variant of 'spright', an archaic form of 'sprite', which itself derives from the middle english 'sprit', meaning 'spirit' or 'elf'. 'sprite' originates from the anglo-norman 'esprit' and old french 'espirit', both stemming from the latin 'spiritus' meaning 'breath, spirit'. the '-ly' suffix is an english adjectival ending. thus, the literal sense of 'sprightly' evolved from 'spirit-like' to connote the lively, energetic, and airy qualities associated with a spirit or elf, resulting in its modern meaning of brisk vivacity.

this word is a simplex form derived from a historical variant. it is not productively segmented into meaningful substrings in modern english.
