singly

the adverb 'singly' is a direct descendant of the adjective 'single', which entered middle english from old french 'sengle' or directly from latin 'singulus', meaning 'one, individual'. the latin term is likely a diminutive or intensive form related to 'simplus' (simple), reinforcing the idea of oneness. the addition of the old english adverbial suffix '-ly' transformed it into a word describing the manner of action—doing things one by one or acting alone. this etymological path from a latin root emphasizing unity to an english adverb describing sequential or solitary action illustrates a clear semantic evolution from a state of being to a mode of operation.

the word is an adverb formed by adding the suffix '-ly' to the adjective 'single'. the adjective 'single' originates from latin 'singulus', meaning 'one, individual, separate'. the suffix '-ly' is from old english '-lice', used to form adverbs from adjectives.
