Ch 1 · Lesson 18

The ます form and the three verb groups

Every verb you have met so far, made polite: , , . And the one rule that sorts verbs into three groups.

The short version

Japanese verbs never change for I, you or they

。。

Tabemasu. Tabemasen: I eat. I do not eat.
Why?

is I eat, you eat, she eats and they eat alike. Japanese verbs carry politeness and tense in their endings, never person. Who is doing it comes from the context, and very often it is simply left out.

The -eru verbs that are not what they look like

うち 。

Uchi ni kaerimasu: I am going home.
Why?

Most verbs ending in -eru or -iru drop the る to make ま: , . A handful look identical but follow the other pattern, and かえる (to go home) is the one you meet first: , not えま. Learn the exceptions as you meet them, not as a list.

That's the gist. The full article goes deeper - more examples, the edge cases, the why - and the practice below scores like a vocabulary session and earns the same XP.
