scarcely

the adverb 'scarcely' is formed by adding the old english adverbial suffix '-ly' to the adjective 'scarce'. the adjective 'scarce' entered middle english from old north french 'escars', which itself likely derives from a vulgar latin root 'excarpsus', meaning 'plucked out' or 'made rare', related to latin 'excerpere' (to pick out). the core semantic journey is from the literal idea of something being picked out and thus becoming rare or insufficient, to the adverbial sense of an action occurring only by a narrow margin or in a barely sufficient manner. this evolution encapsulates a shift from a concrete state of lack to an abstract grammatical function expressing marginal degree or immediacy.

Structure: scarce (insufficient) + ly (adverb suffix) scarce (from old north french 'escars', meaning 'scanty, scarce', of uncertain/romance origin) + ly (from old english '-līċe', an adverbial suffix forming adverbs from adjectives).
