The Old Irish Verb System Is Way Too Complex, Right?

What's weird about old Irish is archaic Irish looks more recognizably Indo European and middle Irish said this is insanity. But it just so happens that this grand period of old Irish literature happened in this extreme, phonetically unsettled period of the language. So you can see in later texts, like certain particles get placed in different or in a different order because, you know, and everything is just being reordered. And then I guess the last one of the preverbs is they can be separated from the verb stem by object pronoun forms. Right? Sometimes that mutation is not reflected in the orthography even better.
