disconcertingly

the adverb "disconcertingly" is built upon the verb "disconcert," which entered english in the late 17th century from the french 'déconcerter'. the french term combined the negative prefix 'des-' (from latin 'dis-') with 'concerter', meaning "to arrange, bring into harmony." the core latin root is 'concertare', meaning "to contend, dispute," but which evolved in romance languages to signify agreement and arrangement. thus, the literal morphemic logic is "to undo an arrangement." over time, the meaning shifted from physically disrupting plans to causing emotional or mental unsettlement. the addition of the adverbial suffix '-ingly' transforms this action into a manner of causing such unsettling feelings.

Structure: dis + concert + ingly - dis- (latin): a prefix meaning "apart," "away," or having a negative, reversing force. - concert (latin via french): from italian 'concertare', meaning "to bring into agreement." in this context, it relates to the sense of "to settle, arrange, or set in order." - -ingly (old english): an adverbial suffix formed from the present participle suffix '-ing' combined with the adverbial suffix '-ly'.
