puellile

Etymology

Formed from Latin puella (“female child, girl”) and English -ile (a suffix meaning ‘capable of; tending to’ that forms adjectives), on the model of puerile. Puella itself derives from puellus (“male child, young boy”) plus -a (the feminine form of -us); puellus is a contraction of puerulus (“little boy; little slave”), from puer (“boy, lad; male page, servant, or slave; child”) — ultimately from Proto-Indo-European *peh₂w- (“few, little; smallness”) — plus -ulus (“suffix forming diminutives of nouns indicating small size or youth”).
