Old English bringan "to bear, convey, take along in coming; bring forth, produce, present, offer" (past tense brohte, past participle broht), from Proto-Germanic *brangjanan (source also of Old Frisian branga "attest, declare, assure," Middle Dutch brenghen, Old High German bringan, German bringen, Gothic briggan). There are no exact cognates outside Germanic, but it appears to be from PIE *bhrengk- (source also of Welsh he-brwng "bring"), which, according to Watkins, isbased on root *bher- (1) "to carry," also "to bear children," but Boutkan writes, "We are probably dealing with a Germanic/Celtic substratum word."
The tendency to conjugate this as a strong verb on the model of sing, drink, etc., is ancient: Old English also had a rare strong past participle form, brungen, corresponding to modern colloquial brung.
To bring about "effect, accomplish" is from late 14c. To bring down is from c. 1300 as "cause to fall," 1530s as "humiliate," 1590s as "to reduce, lessen."
