Etymology
LatinFrenchEnglish
The phrase 'in the affirmative' developed from the Latin verb 'affirmare' (to make firm, to assert), which passed into English through French 'affirmatif'. It has been used in English legal and parliamentary language since the 16th century to describe a formal statement of agreement, as opposed to a negative reply. The pattern 'in the + adjective' (e.g., 'in the negative', 'in the abstract') is a common formal construction borrowed from Latin and French legal phrasing.
