Now, I've got a question related to writing one, in my opinion interesting, word: gnawn as the past participle of to gnaw. Would it be understood, and sound okay, and be perfectly correct? Dictionaries do list this past-participle form of to gnaw, but I'm afraid of it being too obsolete.
- The motor of my old, corroded chainsaw had been completely gnawn by some rust when I came back.
- The stick thrown to that beaver was gnawn by it, as it was very hungry.
