reassuringly

the word "reassuringly" is built upon the verb "assure," which entered english from old french asseurer, itself derived from the vulgar latin assecurāre, a compound of latin ad- and securus (safe, secure). the prefix "re-" was added in english to indicate the action of making someone sure or confident again, often after doubt or fear has arisen. the addition of the adjectival suffix "-ing" creates the participle "reassuring," describing something that performs this action, and the adverbial suffix "-ly" finally modifies it to describe the manner in which an action is done. thus, the literal sense of "making secure again" evolved into the modern meaning of acting in a way that restores confidence or alleviates anxiety.
