foreswear?

[TRex]

In a recent 7-by-many puzzle, 'foreswear' was accepted as a word with all the letters — but even the OED doesn't list this as a word. The closest it lists is forswear.

There are other dictionaries besides the OED, of course. The Free Dictionary has foreswear as a variant of forswear, listing its sources as American Heritage Dictionary of the English Language and Collins English Dictionary – Complete and Unabridged. These are online sources, but my hard copy Merriam Webster's Collegiate Dictionary from 1996 also lists foreswear.
