Etymology

The word "responsible" originates from the Latin responsus, the past participle of respondere ("to answer"), which combines re- (back) and spondere (to pledge, promise). The suffix -ible (able to) was added in Late Latin to form responsibilis, meaning "answerable" or "accountable." Over time, the term evolved in English to denote accountability or duty, reflecting the idea of "answering for" one's actions or obligations.
