The cabinets look GREAT! my compliments.
But, I'd like an explanation of the use of "then" in the place of than. It seems to be a common usage in the U.S. but I have seen it used by at least one Canadian.
I find it confusing, for example..."I'd rather build this, then that." and "I'd rather build this, than that" the 2 statements are very different one describing the order in which they're done and the other describing preference to one over the other.
In U.S. speech is "then" pronounced "than"? If so, how is "than" pronounced?
