r/pali

I have never read a word in Pali.

But I wanted to translate "To our eternity" to Pali and I used an online tool. I got this

තො ඔඋර් එතෙර්නිත්‍ය්

Is this correct? Thanks in advance.

Pretty new to Pali - following Warder's grammar at the moment - so maybe there's something I'm missing, but it would appear that having particular prefixes on a verb root changes the conjugation thereof: vadati is 1st conjugation but abhivādeti is 7th.

I am curious if there is any sort of rhyme or reason to the changing of a conjugation such as this? As I say, being new, I wouldn't be surprised if there's something I'm missing here. Is there perhaps a form such as abhivadati that means something slightly different to abhivādeti?

Any info appreciated! Thanks!
