acidifyingadj.

Brit.

/əˈsɪdᵻfʌɪɪŋ/, U.S.

/əˈsɪdəˌfaɪɪŋ/,

/æˈsɪdəˌfaɪɪŋ/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: acidify v., -ing suffix².

Etymology: < acidify v. + -ing suffix², after French acidifiant (1781 in the passage translated in quot. 1783). Compare slightly later acidifiant adj.

Originally: (Chemistry) combining with other substances to form acids (= acidifiant adj.); chiefly in acidifying principle; now historical. In later use more widely: generating acid, causing increased acidity (cf. acidify v.).
