the word 'succinctly' originates from the latin 'succinctus', the past participle of 'succingere', meaning 'to tuck up, gird from below'. this verb is composed of 'sub-' (under) and 'cingere' (to gird). the literal image is of tucking up one's garments with a belt for freer movement, implying preparedness and efficiency. over time, this concrete notion of being 'girded up' evolved metaphorically into the abstract sense of speech or writing that is 'tightly fastened' or compressed, leaving no excess. the adverb-forming suffix '-ly' was added in middle english, directly from the adjective 'succinct'.

Structure: suc (under, close) + cinct (girded, fastened) + ly (adverb suffix) suc- (variant of 'sub-', from latin 'sub', meaning 'under, close to'), -cinct- (from latin 'cinctus', past participle of 'cingere', meaning 'to gird, surround, fasten'), -ly (from old english '-lice', forming adverbs from adjectives).
