Forms

irresponsable (plural irresponsables)[1]

Etymology

It is formed from French ir- + responsable, with the form of the prefix in- used before /r/.[2][3][4] responsable is a learned formation on Latin responsus, the past participle of respondeō in the sense “to stand surety”.[4] The FEW files it under the Latin verb.[5]

Earliest recorded meaning

It is first found in 1786 in the Promenade de Clarisse, attributed to Beaumarchais, meaning “not answerable for one's acts”.[2][6]

Semantic evolution

Rey notes that it had both its legal and its everyday value from the start.[7] In law it describes someone who cannot be held to account, such as a child, a person of unsound mind or a head of state.[8][6] The common sense, someone who acts without a sense of responsibility, regardless of consequences, is dated 1924 (Gide) by the GLLF, and the Petit Robert attributes it to English influence.[6][8] The noun un irresponsable, a person who acts thoughtlessly, is recorded in 1934, in Duhamel.[7][6] The derivative irresponsabilité (1790) replaced the older non-responsabilité (1784).[7]
