I think that “this morning” and “this afternoon,” when used like “this afternoon I am going to the doctor” or “what are you doing this afternoon?” should be changed to a one-word contraction or merge of some sort. “Thisafternoon” just seems to roll off the tongue better than “this” “afternoon.”
Although, it would not work as well if you were trying to describe the afternoon as its own thing. For instance, “this afternoon is dragging” could not use the merged “thisafternoon”.
I don’t really know what part of speech my first example would fall under; a preposition, maybe? (I don’t even know what to look for to look it up.) But it does not seem like the most outlandish thing ever proposed, so who knows? Maybe it’ll catch on. Or not, since spell check doesn’t like it.
Any words that you think need to be merged, modified, etc? Do you agree with my “thisafternoon” proposal?
