[challenge] I actually think instances of verbed nouns-not-usable-as-adjectives are even rarer than instances of verbed adjectives-not-usable-as-nouns. However, I did find an example of a verbing of a non-adjectival noun: You can tree a cat. BTW Calvin's only 12 years younger than I am. He'd be 26 sometime this year. Yeesh!
[SM] I live and learn - I'd never seen "tree" as a verb before, other than in the sense that "the copse was heavily treed", but have found now found it in the dictionary. I may have to try and get this sense into normal conversation tomorrow
(Phil) I hope it doesn't replace "woooded". I agree "ornate" as a verb is monstrous when "ornament" already exists as a verb. (SM) How do you tree a cat? Stick a twig up its bum? You'll be lucky. I can see how you can de-cat a tree, though, even if it might need the Fire Brigade.
[Phil] I never saw it before, until I googled it in a spirit of misunderestimation. The OED has it as an obsolete verb, which I suppose is why an antiquarian map dealer might use it to ornate his prose. But as Caxton writes, "Somtyme ornatynge of wordes maketh the proposycion to be withdrawen fro the trouthe."
It's usually mixed up in some way to even both sides out. Things have quieted down. Dual the A11!
