I have noticed a trend in some rap music where erry replaces the word every (see 1:35 of "The Motto" by Drake). Can anyone shed light on the origins of this pronunciation?
I thought it might trace to Southern (U.S.) rappers, although Drake is Canadian. I'm not sure if there's a regional basis, or if perhaps it spread through the subculture to facilitate rhyming. Is it considered Black Vernacular English? Can anyone provide some details about its origin–the dialect it may have come from or artists that may have propagated it?
