Is it appropriate to use a comma in the expression: ..."from the ground, up" or should there be no comma?
Without a comma, the expression seems strange to me. I've been criticized by a non-native English speaker for writing the expression in this way. Since he's put a lot more effort into learning the "rules" of English, I have a shadow of self-doubt. However, I have a feeling that this is one of the many (many) cases where English proves that rules were meant to be broken - or at the very least, that there are more rules than one can easily learn.
