Understanding Jamaicans : This is for fun. Jamaicans use "ah " in place of words like " to, is, it will, " . I read this is the main preposition for ....everything. This even replaces combined words like "ah lie" = " I am telling the truth" / "you have to be joking" / " I am not lying" .
Hope this helps when listening to your fav Reggae song .
