Okay, so let's say you have the verb понимать (to understand), you would use the simple 'ть' conjugation correct?

For example: Я понимаю, Ты понимаешь, Etc...

But, for the verb слышать (to hear) it uses the other type of conjugation.

For example: Я слы́шу, Ты слы́шишь, Etc...

So if they both end in 'ать' why do you conjugate them both differently!?

Somebody please help to explain this to me because I am getting frustrated. Lol, thank you!
