In a separate answer, I was trying to use ait in an English sentence:
If the Lex Julia can ait its wording…
…but I ran into a problem. Even ignoring my bastard mixture of English and Latin, "can ait" sounds deeply wrong to me, just like *potest ait; an infinitive would be better.
Ait, however, doesn't seem to have any sort of infinitive.
What should I do in cases like this, where an infinitive is grammatically needed? For example, possum negāre = "I am able to deny this"; how would I say the opposite, "I am able to affirm this", in natural-sounding Latin?
