the adverb 'tellingly' is built upon the old english verb 'tellan', which originally meant 'to count' or 'to recount a narrative'. the addition of the '-ing' suffix transforms the verb into an adjective, 'telling', which describes something that communicates effectively or reveals a significant point. finally, the old english adverbial suffix '-ly' is appended, converting the adjective into an adverb that describes the manner of an action. thus, the word's literal progression from 'to count/recount' to 'revealingly' illustrates how a basic act of narration evolved to signify a powerful mode of communication that conveys unspoken truths or significant implications.
