Hello, welcome to this course. I'm Junko, a Japanese language tutor.
I have been teaching Japanese online for several years.
I enjoy teaching Japanese to learners from various countries every day.
In this course, I will explain various verb forms learned in the beginner level of Japanese.
I'll also introduce some grammar using these forms.
And I'll explain things slowly for those who don't have English as their first language.
About Japanese verb forms.
Japanese verbs can change their meaning in various ways with the mass form as the foundation.
When learning verbs, something mass represents the polite form of verbs,
while friends might not use the polite form with each other.
As a Japanese language learner, if you are ever unsure which form to use,
opting for the mass form can be a language learning strategy.
It's never considered impolite.
It's not always necessary to learn verbs starting from the mass form.
When dealing with various verb conjugations,
it's just that starting from the mass form can often be more straightforward to understand.
Japanese verbs can be classified into three groups.
Let's take a look at the differences in each one.
Let's start with the explanation of group 3.
Group 3 verbs in Japanese consist of only two.
SHIMASU and KIMASU.
However, there are expressions like
BENKYOU SHIMASU, SHOKUJI SHIMASU, MOTTE KIMASU,
TSURETE KIMASU, which involve noun and then SHIMASU,
verb, te-form, and then KIMASU.
So don't get confused.
For example, TABEMASU is a group 2 verb.
You can change the mass part into various forms.
For instance, in the te-form, TABEMASU becomes TABETE.
TA-form, TABETA.
NAI-form, TABENAI.
Like it.
Finally, group 1 verbs.
For example, let's take the verb KAKIMASU and make the negative form.
Change the vowel I before mass to a, so KAKI becomes KAKA,
and then add NAI to get KAKANAI.
In this way, there are several rules for each group of verbs.
In this course, you will learn how to make various verb forms.
However, when having conversations or writing sentences,
it can be time-consuming to construct sentences while using each form.
Therefore, for commonly used verbs,
it's a good idea to memorize not only the mass form but also other forms.
In our lesson, first, I will explain the primary meaning and usage of the form within sentences.
Then, I introduce how to make the forms.
Finally, I provide an introduction to various grammar points using those forms.
Now, let's proceed to learn some grammar using these forms.
TE-form is primarily used in sentences when making requests
or indicating the continuation of an action.
However, this is just a general guideline, and it doesn't cover all possible uses.
For example,
Please do something is a request.
I eat during something indicates that an action is ongoing.
So, for this, we use the verb TE-form.
Here is the explanation of the TE-form for group 3 verbs.
For group 3 verbs, there are only two, SHIMASU and KIMASU.
The TE-form of SHIMASU is SHITE, and the TE-form of KIMASU is KITE.
There are no specific rules. You should simply memorize them.
BENKYOU SHIMASU becomes BENKYOU SHITE.
KAIMONO SHIMASU becomes KAIMONO SHITE.
MOTTEKIMASU becomes MOTTEKITE.
TSURETEKIMASU becomes TSURETEKITE.
Here is the explanation for the TE-form in group 2 verbs.
To make the TE-form for group 2 verbs, you simply replace MASU with TE.
TABEMASU becomes TABETE.
MIMASU becomes MITE.
OBOEMASU becomes OBOETE.
Explanation for the TE-form in group 1 verbs.
Group 1 verbs are a bit complex. There are as many as 5 patterns.
When the stem before MASU ends in KI, the KI changes to ITE.
KAKIMASU, KAITE.
KIKIMASU, KIITE.
HATARAKIMASU, HATARAITE.
While IKIMASU has KI before MASU, it's an irregular case, and it becomes ITE, not IITE.
When the stem before MASU ends in GI, the GI changes to IDE.
OYOGIMASU, OYOIDE.
ISOGIMASU, ISOIDE.
When the stem before MASU ends in MI or BI, the MI or BI changes to NDE.
YOMIMASU, YONDE.
NOMIMASU, NONDE.
YOBIMASU, YONDE.
ASOBIMASU, ASONDE.
Both YOMIMASU and YOBIMASU, when in the TE-form, becomes YONDE.
When the stem before MASU ends in I, CHI or RI, the I, CHI or RI changes to ITE.
AIMASU, ATTE.
KAIMASU, KATTE.
TETUDAIMASU, TETUDATTE.
MATSHIMASU, MATTE.
MOCHIMASU, MOTTE.
KAERIMASU, KAETTE.
OWARIMASU, OWATTE.
When the stem before MASU ends in SHI, the SHI changes to SHITE.
HANASHIMASU, HANASHITE.
KAESHIMASU, KAESHITE.
KESHIMASU, KESHITE.
Group 1 and group 3 SHIMASU, SHITE are often confused.
Please don't get confused.
A very important point for TE-form in group 1.
It can be confusing to determine whether a word belongs to group 1 or group 2,
but you will have to memorize them one by one.
One hint is that if the character before MASU is not KI, GI, MI, I, I, CHI, or I,
it is often in group 2.
Also, for example, OKIMASU, get up, is in group 2,
and OKIMASU, put on, belongs to group 1.
They are different group of verbs with different meanings.
Grammar using the verb TE-form.

Paspouto wo misete kudasai.
Asa desu.
Okite kudasai.

Barabute kudasai is a polite expression.
If you want to say it casually, you can remove kudasai.

Two or more sentences can be joined together using barabute.
Tense is indicated by change it at the end of the sentence.
Beginner say

You can say it in one sentence using barabute, barabute structure like this.

Ofuro ni haitte, ha wo migaite, nemasu.
Tomodachi ni atte, kaimono shite, karaoke ni ikimashita.
Kotoshi no natsu wa kawa ni itte, sakana wo tsutte, sore wo tabetai desu.
Sentence 1 barabute kara sentence 2
The phrase is used when taking the action in sentence 2 after the action in sentence 1.
Souji wo shite kara kaimono ni ikimasu.
Denki wo keshite kara ie wo demasu.
Sukoshi yasunde kara dekakemasu.
Oyoide kara aisukurimu wo tabemasu.
Barabute imasu.
It indicates that something is ongoing or continuous.

Gohan wo tabete imasu.
Tomodachi wa denwa wo kakete imasu.
To show a state.
Kekkon shite imasu.
Nihon ni sunde imasu.
Watashi wa Yamada-san wo shitte imasu.
Shitte imasu is a te-form of shirimasu and is typically used to express I know.
On the other hand, shirimasen is used to indicate I don't know.
And it's important to know that it's usually used in its masu form.
You wouldn't say shitte imasen to mean I don't know.
Instead, you'd use shirimasen for the purpose.
Shitte imasu.
Shirimasen.
Shitte imasu ka?
Shirimasen ka?
To show a habitual action.
Mai asa, jogging wo shite imasu.
Mai ban, hon wo yonde imasu.
Toyota wa, kuruma wo tsukutte imasu.
Konbini de, mizu wo utte imasu.
Otto wa, Google de hataraite imasu.
Nihongo no gakkou ni kayotte imasu.
Intransitive verb te imasu.
Used to describe the state of noun.
This grammar requires a bit of attention.
It used intransitive verbs rather than transitive verbs.
I won't go into detail about intransitive and transitive verbs here.
The case is where verbs belong to different groups,
such as intransitive and transitive verbs exit.
Let's list some examples of intransitive and transitive verbs.
Akemasu.
Akimasu.
Kesimasu.
Kiemasu.
Orimasu.
Oremasu.
Doa ga aite imasu.
Inu ga nete imasu.
Tomodachi ga waratte imasu.
Verb te arimasu.
The intransitive verb te imasu grammar express the state of the noun.
On the other hand, the transitive verb te arimasu grammar
used transitive verbs to also describe the state of the noun,
but with a nuance that someone did it intentionally.
What is the difference between doa ga aite imasu and doa ga akete arimasu?
Doa ga aite imasu simply indicates that the door is in an open state.
It doesn't specify who opened it or whether it opened on its own.
Doa ga akete arimasu, on the other hand,
implies that the door has been intentionally opened either by the speaker or someone else.
Tsukue ni pasokon ga oite arimasu.
Karenda ni yotei ga kaite arimasu.
Kagi ga kakete arimasu.
Verb te shimaimasu.
Verb te shimaimashita.
It is used when an action is completed at a specific point in time or has already ended.
Completed at a specific point in time or has already ended.
Kyoujuu ni kadai wo yatte shimaimasu.
Okashi wo zenbu tabete shimaimashita.
Mou yonde shimaimashita ka?
The speaker, when experiencing regret or disappointment.
Paspouto wo nakushite shimaimashita.
Fuku ga yaburete shimaimashita.
Tomodachi ga kuni e kaette shimaimashita.
It is used when a necessary action or task will be completed by a specific time.
Kore kara sakka wo shimasu kara, mizu wo nonde okimasu.
Ryokou no mae ni, hotel wo yoyaku shite okimasu.
Jugyou no mae ni, fukushuu shite okimasu.
The grammar verb te okimasu with okimasu referring to the group 1 verb to put.
So, when used with please verb te kudasai, it becomes verb te oite kudasai.
To get up, okimasu is a group 3 verbs.
Don't get confused.
Koko ni oite oite kudasai.
Koko ni oite okimasu.
When the action isn't yet completed, we use verb te imasen.
Mada verb te imasen.
Mada desu.
Mou gohan wo tabemashita ka?
Mada tabete imasen.
There are also other grammatical structures that are used with te form.
Here, I've introduced 10 of them.
Ta form.
It's privately used to express past actions,
events that have been completed, or states that existed in the past.
This is just a rough idea.
Not an exhaustive list.
The ta form is made in the same way as the te form.
Shimasu, shita, kimasu, kita.
To make the ta form for group 2 verbs, you simply replace masu with ta.
Tabemasu, tabeta, oboemasu, oboeta.
Sutemasu, suteta.
Explanation for the te form in group 1 verbs.
As we learned with the te form in group 1,
it can be a bit confusing with 5 different patterns.
When the stem before masu ends in ki, the ki changes to ita.
Okimasu, oita.
Hatarakimasu, hataraita.
Ugokimasu, ugoita.
Similarly to the te form, ikimasu is irregular.
And it becomes itta in its te form.
It is not iita.
When the stem before masu ends in gi, the gi changes to ita.
Oyogimasu, oyoida.
Isogimasu, isoida.
When the stem before masu ends in mi or vi, the mi or vi changes to nda.
Yomimasu, yonda.
Nomimasu, nonda.
Yobimasu, yonda.
Asobimasu, asonda.
When the stem before masu ends in ichi or ri, the ichi or ri changes to ita.
Kaimasu, katta.
Tetsudaimasu, tetsudatta.
Tsukaimasu, tsukatta.
Kachimasu, katta.
Machimasu, matta.
Tachimasu, tatta.
Tsukurimasu, tsukutta.
Owarimasu, owatta.
Magarimasu, magatta.
When the stem before masu ends in shi, the shi changes to shita.
Hanashimasu, hanashita.
Dashimasu, dashita.
Kashimasu, kashita.
When the stem before masu ends in shi, the shi changes to shita.
Hanashimasu, hanashita.

Kashimasu, kashita.
Similar to the te-form for the ta-form, let's use the following hint.
If the verb doesn't end in ki, gi, mi, bi, i, chi, ri, or shi before masu, it is often in group 2.
Grammar using the verb ta-form.
The ta-form of verbs such as itta is used to casually express the past or completion of an
action in Japanese. For example, ikimashita is a polite form while itta is a casual form.
Kaimashita, katta, wakarimashita, wakatta, mimashita, mita, tabemashita,
tabeta, benkyoushimashita, benkyoushita.
Verb ta-koto ga arimasu is used to indicate that you've had the experience of a past action.
Nihongo wo naratta koto ga arimasu.
Fuji-san ni nobotta koto ga arimasu.
Natto wo tabeta koto ga arimasu.
Koko ni musume wo tsurete kita koto ga arimasu.
Iro ni tsuite kenkyuu shita koto ga arimasu.
Kekkon shite ita koto ga arimasu.

Verb te, verb te, something.

This sentence, there is no other information for the listener to imagine.
Kinou wa, terebi wo mitari, heya no souji wo shitari shimashita.
It suggests that there were other actions in addition to watching TV and cleaning,
mentioning two or three activities among them.

If verb, tara ii desu is just advice.
Then, verb, tahou ga ii desu, simply that it's not good to not take the action.
The phrase, it's plural to verb, after used with yo added at the end of the sentence,
emphasizes non-mechanical conversation and impressions.
Kaze desu ka?

It's used when you request the same thing you've shown or mentioned.
Mita touri ni, kanji wo kaite kudasai.
Naratta touri ni, karei wo tsukurimasu.
Sensei kara kiita touri ni tsutaemasu.
In addition to using the verb ta form, you can also express the same thing using a noun.
Sen no touri ni, kono kami wo kitte kudasai.
Setsumeisho no touri ni, kumitatemashou.
Verb, ta ato de, verb to.
It indicates that after verb one happened, verb two occurred.
There is a similar expression, verb one, te kara verb two.
Verb one, te kara verb two implies that the action of verb one is a pre-request or a condition for verb two.
On the other hand, verb, ta ato de, has a weaker sense of such meaning
and simply presents information that something happened after some action.
In actual conversation, both are often used within our Korean distinction.
Hashitta ato de, shabaa wo abimasu.
Heya wo souji shita ato de, nakushita mono ga mitsukarimashita.
Tomodachi ni, denwa wo kaketa ato de, ie wo demasu.

There are also other grammatical structures that use the ta form.
Here, I've introduced seven of them.

It's a casual form of verb something masen.
So, for example, a casual form of tabemasen is tabenai.

Imperative form
You want expressions for making requests using verb TE kudasai.
I explained that if you omit kudasai and simply say verb TE,
it becomes a more casual way of speaking.
The imperative form carries a stronger tone and is often used by men.
Women tend to use verb TE more frequently than the imperative form.
However, it can vary depending on the situation and the individual.
