I'm having trouble understanding conjugation.
Mainly, because i'm using My japanes coach, and while it's good for increasing vocabulary and writing, it's doing a HORRIBLE job with the transition to japanese.
It's explaining conjugation with Romaji characters.

Anyhow. It mentions these "bases". Seven of them in total.
Could anyone be so kind as to explain Conjugation using Bases instead of Romaji? i can't seem to find a pattern there.
