what the different te and tte?


hello minasan konnichiwa, what the different te and tte? what te = ( e ru and
i ru) or to another? and tte =(a, o , u ru)?

because some word i can fine like hairu ( to come in ) become haitte, why not
haite?

thanks, arigatoo




Verbs conjugate pretty cleanly depending on their type, as [explained in
Wikipedia for the te-
form](https://en.wikipedia.org/wiki/Japanese_verb_conjugation#te_form). E.g.
all godan verbs ending in -る (e.g. 入る) become -って (入って).
