It is not known where it ultimately came from; it is evidently connected with Old High German iba ‘condition’ and Old Norse ef ‘doubt’, but whether it started life as a noun like these or was from the beginning a conjunction is not clear. Its surviving Germanic relatives are German ob ‘whether’ and Dutch of ‘if’.if (conj.)Old English gif (initial g- in Old English pronounced with a sound close to Modern English -y-), from Proto-Germanic *ja-ba (cognates: Old Saxon, Old Norse ef, Old Frisian gef, Old High German ibu, German ob, Dutch of "if, whether"), from PIE pronominal stem *i- [Watkins]; Klein, OED suggest probably originally from an oblique case of a noun meaning "doubt" (compare Old High German iba "condition, stipulation, doubt," Old Norse if "doubt, hesitation," Swedish jäf "exception, challenge"). As a noun from 1510s." |
