形Verbs and descriptions

Verb forms

Every verb changes form to show tense, politeness and negation. Learn the three groups and you can handle almost all of them.

All lessons

The four polite forms

ます changes, the stem stays

These are safe with almost anyone and easy to form once you know the stem.

Now or futurePast
Yes食べます食べました
No食べません食べませんでした

The four plain forms

Used with friends, and inside longer sentences

The plain form with る or う is the “dictionary form”, the one you'll look up.

Now or futurePast
Yes食べる食べた
No食べない食べなかった

Three groups

How do you know which group a verb is in?

Some verbs look like group 2 but belong to group 1, such as 帰る, 入る, 知る and 走る.

GroupHow to spot itExamples
Group 1Ends in any う sound, or often る after a, u or o書く, 飲む, 話す, 買う, 取る
Group 2Ends in いる or える and keeps its stem食べる, 見る, 寝る, 起きる
IrregularJust these twoする, 来る

Pick a verb

Each row shows how the polite and plain forms line up.

書(か)きます、書(か)かない、書(か)いた。Kakimasu, kakanai, kaita.

writes, doesn't write, wrote

Group 1 changes its last sound: -i before ます, -a before ない.

Odd ones out

A few to memorize

行く is a regular group 1 verb except that its past is 行った. ある has the negative ない, not あらない. Forms like ます and ない also say something about who you're talking to, so you'll usually hear plain forms only among friends or family.
