Dang, not even in there?

Wait, the OED does cite a usage of it:

  1. acceptor, n. View full entry 1665

...uld (if he could) unaccept the Bill , or make voyde his Acceptanc...

1665, so it exists, but it's vintage?

I guess it depends on who you ask.

You shouldn't fault your spell checker for flagging it. No one has any real authority to tell you not to use it but it is certainly not popular enough that you should use it unawares.

Unawares is a word right?
