-izo suffix in Latin?

An exception fell out of my note as I was writing it, leaving my first sentence slightly incorrect: citharizo is used by Nepos; I believe it is a very rare example of an -izo verb in Classical Latin.

I'm not very familiar with Ancient Greek compared to Latin, so I'll continue to add -izo as a suffix for now. Once I've gone through all the verbs, I'd welcome it if you could check the -izo verbs for any Greek ones they might have been borrowed from. We can see if there are any that are left over.

At the same time, I'll add Greek entries where it seems applicable, if I happen to get to this early. Feel free to overwrite if you are working very systematically, and we can sort it out in the end. I suspect the real question will be where an eventual -izo Latin suffix ends being labelled on the spectrum between Late Latin and New Latin, given how defective that spectrum is for this type of question.

I'm just going through the Latin verbs in alphabetical order, so I would call that systematic.

I noticed. I will probably to do the Greek -izo verbs I can identify today all at once. I really do not mind if you overwrite by accident because they'll all be in a small category anyway.

I was able to find Greek analogues for most of these words, though a few are disfavoured variants. There are two examples which might be autochthonous to Latin: allegorizo and organizo. They are both extremely rare. I would welcome any improvements to the etymological notes; I am not satisfied with a few of them. You do find such interesting things, going alphabetically through the dictionary.
