Present and Past Polite Forms
This article describes the polite verb form, often called the -masu form.
The polite form of Japanese verbs is used in normal polite language. It is often used when talking with colleagues, teachers, doctors, people older than you, or people you do not know well.
Only the main verb of a sentence (the one at the end of the sentence) occurs in polite form.*
The polite endings are added to the stem of ichidan (ru-dropping) verbs, and to the stem ending in the "i" vowel sound of godan (u-dropping) verbs (see Verbs). They are as follows:
| -masu |
polite present |
Note: also used for the future |
| -masen |
polite negative |
Used, like -masu, for both present and future |
| -mashita |
polite past |
|
| -masen deshita |
polite negative past |

Polite present
ときどき映画を見ます。

Polite negative
たかはしさんは魚を食べません。
Takahashi san wa sakana o tabemasen.

Polite past
毎日漢字の勉強をしましたが、すぐ忘れました。
Mainichi kanji no benkyou o shimashita ga, sugu wasuremashita.
I studied kanji every day, but I soon forgot them.
Polite negative past
一時間待ましたが、友達は来ませんでした。
Ichi-jikan machimashita ga, tomodachi wa kimasen deshita.
I waited an hour, but my friend didn't come.
If a sentence ends in the word "desu" or one of its forms, it is also a normal polite sentence. The other forms of "desu" are:
| negative |
de wa** arimasen / ja arimasen |
| past |
deshita |
| negative past |
de wa** arimasen deshita / ja arimasen deshita |
*When two sentences are connected by a conjunction, such as ga (but), both may end in a polite form verb.
**In kana, this "wa" is written は.
