In the 1970s, singer Neil Diamond sang a song that included the words Song she sang to me, Song she brang to me, Words that rang in me….
Now, I’m not averse to giving an artist a little poetic license, but as for the rest of us, let’s just stick to standard English. Bring is an irregluar verb, that is, a verb that has its own particular conjugations rather than following the same pattern followed by other verbs. That irregular pattern might not seem logical to us, or we might not like the pattern; nevertheless, it’s the correct pattern.
Despite how many times I’ve heard brang and brung uttered not only in the Neil Diamond song but also in everyday conversation, there is no brang or brung in the conjugation of bring. The correct pattern is bring, brought, has/have brought.
I bring my portfolio to every job interview.
She brought the baby home in a white blanket (not She brang the baby home).
He has brought enough donuts for the entire department (not He has brung enough donuts).
