briefly

The word 'briefly' is a straightforward adverbial formation from the adjective 'brief'. The adjective 'brief' entered English via Old French brief from Latin brevis, which carries the fundamental meaning of 'short' in terms of space, time, or speech. The Proto-Indo-European root mregh-u-, meaning 'short', is the ultimate ancestor, giving rise to related words like Latin brevis and Greek brakhys. By adding the Old English adverbial suffix '-ly', which denotes 'in the manner of', the word 'briefly' was created to specifically describe an action performed in a short time or expressed with conciseness, directly extending the core sense of its Latin-derived root into the grammatical domain of adverbs.

Structure: brief (short) + ly (adverb suffix) - brief: From Latin brevis (short). The core adjective meaning 'short in duration or extent'. - ly: From Old English -līce (forming adverbs from adjectives). The suffix indicating manner or quality.
