That ought to raise a few eyebrows, but at least it won’t be for poor diction. (Also: Honestly? I’m not in the least bit loath to make that admission. There. I said it.)
Loath is an adjective; it means “unwilling to do something because it’s disagreeable for some reason.” I’m loath to eat raw octopus because the texture is offensive to me.
The unabridged Merriam-Webster online dictionary indicates that (much to the frustration of many copy editors) “loathe” is an alternate spelling.
Why does that frustrate some of us? Because, you see, loathe is the verb.There is no alternate spelling for the verb. It’s loathe. That’s it. And it means “detest, abhor.” I loathe the fact that “loathe” is an alternative spelling for loath.
I may be loosening up a little more in my pragmatic grammarian stance, continuing my journey toward descriptivism, but I still loathe this particular situation.
