the adverb 'summarily' is built upon the adjective 'summary,' which originates from the latin summarius, meaning 'of or pertaining to the sum or total.' this latin term derives from summa, the 'sum, total, or essence' of something. the core semantic evolution moved from the idea of a concise account capturing the total or gist of a matter to the manner of acting—promptly and without the formalities of a full process. the adverbial suffix '-ly,' of old english/germanic origin, was attached to form a word describing an action performed in a concise, immediate, or efficient manner.

Structure: summary (concise) + ly (adverb suffix) summary (from latin summarius, from summa 'sum, total'); ly (from old english -līce, forming adverbs from adjectives).
