I assume that people who read this blog are, more often than not, fansub watchers. So for the first lesson today, instead of talking about “watashi wa John desu”, I’ll begin with something slightly more advance.

Part I: Verb Groups

Anyway, verbs. There are three main categories of verbs in Japanese and they are usually referred to as “Group 1”, “Group 2” and “Group 3”. Creative names huh. Usually when you start to learn Japanese as a foreigner, all the verbs you encounter end with “-masu”, such as ikimasu and tabemasu The truth is, the “-masu” suffix is a tense and you will never find the word “ikimasu” in a dictionary. The words are actually iku and taberu.

I will be presenting all the examples using the dictionary form and I will explain how and why they are converted to the “-masu” form.

Examples

Group 1
打つ utsu
読む yomu
聞く kiku
突っ込む tsukkomu
戸惑う tomadou
犯だokasu
死ぬ shinu
当たる ataru
帰る kaeru
入る hairu
切る kiru
ある aru
行く iku

Group 2
消える kieru
着る kiru
奏でる kanaderu
逃げる nigeru
変える kaeru
いる iru
食べる taberu
寝る neru
借りる kariru
萌える moeru
焼ける yakeru
分ける wakeru
生きる ikiru
生まれる umareru

Group 3
ãã‚‹ suru
くる kuru
存在ãã‚‹ sonzai suru
性交ãã‚‹ seikou suru
浮気ãã‚‹ uwaki suru
変更ãã‚‹ henkou suru

I think if I leave you to stare at the examples long enough, you will see some pattern as to how the groups are determined. There are some exceptions of course, but generally the pattern is easy to understand. And for those of you who read Japanese, yes some of the examples are meant to be weird. ;)

Group 3

First things first, let’s get the easiest group out of the way.

There are only two Group 3 verbs: くる kuru (“to come”) and ãã‚‹ suru (“to do”). The rest are just various combinations of noun + suru (literally “to do [noun]”).

Simple huh.

As for differentiating Group 1 and Group 2 verbs, the first rule of thumb is by the last hiragana character.

Group 1

Group 1 verbs end with one of the following hiragana:
う　く　ぐ　ãã€€ã¤ã€€ã¬ã€€ã‚‹ã€€ã‚€ ぶ
u ku gu su tsu nu ru mu bu

Group 2

Group 2 verbs always end with ã‚‹ ru.
The second last hiragana in a Group 2 verb will always have either a trailing “e” (read “ei” like “A” in “ABC”) or “i” (read “yi”, like “E” in “EFG”) sound. For example, 分ける wakeru.

General Guidelines

A verb that ends with anything but -ru is ALWAYS Group 1, but the reverse is not true. 当たる ataru ends with a -ru, but it is Group 1 and not 2 because the second last hiragana does not have a trailing “e” or “i” sound. 帰る kaeru, 入る hairu and 切る kiru on the other hand all fulfill the Group 2 requirements, but yet they are in Group 1. As with all language rules, there are exceptions and there is no way around it but pure memorization.

Note that all the rules only apply for the dictionary form of verbs. The trailing hiragana changes depending on the tense, in which case it will not match the ones above. But if you are certain that a word is in its dictionary form and yet the last hiragana does not fit any of those listed above, then it is most likely not a verb.

If you observe the kanji and the trailing hiragana for each group, you can probably notice a better way to differentiate the two groups, but I am not going to cover it because it is somewhat more confusing (for those who want to try, the only exception for that rule is 寝る neru being in Group 2).

Review

Let’s say you encounter the verb 泳ぐ oyogu (“to swim”)

First you check the trailing hiragana: ぐ gu
Result: Group 1. Only Group 1 verbs can end with -gu.

Another example: 叱る shikaru (“to scold”).

First you check the trailing hiragana: ã‚‹ ru
Result: Inconclusive, -ru can be found in both groups.

Then you check the second last hiragana: か ka (叱る when written out in full hiragana is しかる)
Result: ka does not end with a trailing “e” or “i” sound, therefore 叱る shikaru is Group 1.

It’s pretty simple, you just have to remember the exceptions that end with -iru or -eru and yet are in Group 1. Some common exceptions are 帰る kaeru (“to return home”), 入る hairu (“to enter”) and 切る kiru (“to cut”).

Exercise

Using the rules I’ve given above, try to group the following in Group 1 or 2.

1. 騒ぐ sawagu Group 1.
2. 入れる ireru Group 2.
3. 変わる kawaru Group 1.
4. 占う uranau Group 1.
5. 回る mawaru Group 1.
6. 避ける sakeru Group 2.
7. 痛む itamu Group 1.
8. 焼く yaku Group 1.
9. 生かだikasu Group 1.
10. 欠ける kakeru Group 2.
11. éã‚Šã‚‹ oriru Group 2.
12. 打ち合わせる uchiawaseru Group 2.
13. 試だtamesu Group 1.
14. 猫みみ nekomimi Not a verb. Neko Mimi Mode desu~~~
15. ぶっ掛ける bukkakeru Group 2. It’s really a verb.

Part II: “-masu” Form

I will spend the second half of this introduction to Japaese verbs by teaching the -masu form. Most language schools teaching Japanese as a foreign language will actually start with the -masu form first before teaching the dictionary form.

This is due to two main reasons. The first is because the -masu form is much more polite than the dictionary form. In fact, -masu is also known as the polite form. So by teaching a foreign student who has just started learning Japanese the polite form first, he or she would not go around offending people unknowingly. Tense manipulation in the polite form is also simpler.

Conversion

Here’s how you convert dictionary form to polite form.

Group 1

Example: 咲く saku (“to blossom”)

Assuming you know your hiragana table, take the trailing hiragana from the verb, which is く ku in this case, and match it with the hiragana that is in the same row but has a trailing “i” sound. What we want is ki.

The “k-” row: か　ka　き　ki　く　ku　け　ke　こ　ko

Replacing ku with ki and add masu to the end, and viola! We get 咲きまだsakimasu. This works for all Group 1 verbs.

Other examples:

打つ utsu = 打ちまだuchimasu
読む yomu = 読みまだyomimasu
聞く kiku = 聞きまだkikimasu
突っ込む tsukkomu = 突っ込みまだtsukkomimasu
戸惑う tomadou = 戸惑いまだtomadoimasu
犯だokasu = 犯しまだokashimasu
死ぬ shinu = 死にまだshinimasu
当たる ataru = 当たりまだatarimasu
帰る kaeru = 帰りまだkaerimasu

Group 2

Too simple. Just take off the trailing ã‚‹ ru and replace with masu

Examples:

消える kieru = 消えまだkiemasu
着る kiru = 着まだkimasu
奏でる kanaderu = 奏でまだkanademasu
逃げる nigeru = 逃げまだnigemasu
変える kaeru = 変えまだkaemasu
いる iru = いまだimasu
食べる taberu = 食べまだtabemasu

Group 3

There are only two of them, so just memorize.

ãã‚‹ suru = しまだshimasu
くる kuru = きまだkimasu
存在ãã‚‹ sonzai suru = 存在しまだsonzai shimasu
性交ãã‚‹ seikou suru = 性交しまだseikou shimasu

Polite Past Tense

“I went.”

This is pretty easy too. Just change the suffix from masu to mashita, no matter which group it is. This applies to polite form only. I will be covering tenses for dictionary form at a later date.

読みまだyomimasu = 読みました yomimashita
消えまだkiemasu = 消えました kiemashita
しまだshimasu = しました shimashita

Polite Negative

“I [will not / do not] go.”

Japanese does not differentiate between “will not” and “do not” and uses negative in both cases. Again, what I have here is for the polite form only. The normal negative form will be covered at a later date. Simply replace all masu with masen

読みまだyomimasu = 読みません yomimasen
消えまだkiemasu = 消えません kiemasen
しまだshimasu = しません shimasen

Polite Negative Past

“I did not go.”

This is simply a matter of adding deshita to the end of the polite negative form.

読みまだyomimasu = 読みませんでした yomimasen deshita
消えまだkiemasu = 消えませんでした kiemasen deshita
しまだshimasu = しませんでした shimasen deshita

Review

Converting to and from polite form is pretty easy so I won’t make an exercise for it. Or I’m just too lazy to. :3 You just have to remember the two Group 3 verbs and the general rule for the Group 1 verbs. Even a chimpanzee can convert Group 2 verbs to polite form.

Similarly, converting from polite present to polite past, polite negative or polite negative past is a simple matter of following the general rule. There are no exceptions for these three rules. Hurray.

Conclusion

In the first chapter, we talked about:

1. Verb groups
2. Dictonary form
3. Polite / “-masu” form
4. Polite past, negative and past negative

Have fun~ Check back some time again for the second chapter if I ever get to writing it. Turns out I did finally write it… Click on the link below.

P.S. I do realize that the pictures have nothing to do with the topic… ;)
