the word 'sufficiently' is built upon the latin verb sufficere, which literally meant 'to put under, to supply, or to be adequate'. this verb combined sub- (up to, under) and facere (to make or do), conveying the idea of doing something up to a required point. the latin present participle stem sufficient- gave rise to the english adjective 'sufficient', meaning 'adequate'. the addition of the adverbial suffix '-ly', of old english origin, transformed it into 'sufficiently', specifying the manner of being adequate. thus, the modern adverb retains the core logic of its ancient roots: doing or being enough to meet a need.

Structure: suffici (do enough) + ent (adjective suffix) + ly (adverb suffix) - suffici: from latin sufficere, meaning 'to supply, be adequate', itself from sub- 'under, up to' + facere 'to make, do'. - ent: a latin-derived suffix forming adjectives, meaning 'being in a state or condition'. - ly: an english suffix forming adverbs from adjectives, denoting manner or degree.
