Word Origin and History for begin
v.

Old English beginnan "to begin, attempt, undertake," a rare word beside the more usual form onginnan (class III strong verb; past tense ongann, past participle ongunnen); from bi- (see be-) + West Germanbic *ginnan, of obscure meaning and found only in compounds, perhaps "to open, open up" (cf. Old High German in-ginnan "to cut open, open up," also "begin, undertake"), with sense evolution from "open" to "begin." Cognates elsewhere in Germanic include Old Frisian biginna "to begin," Middle Dutch beghinnen, Old High German beginnan, German beginnen, Old Frisian bijenna "to begin," Gothic duginnan.
