The te-form (て形, te-kei) is a fundamental and versatile verb form in Japanese. Think of it as the glue that holds your sentences together, allowing you to connect actions, express reasons, make requests, and so much more. This lesson introduces the te-form and its most basic function: linking actions sequentially. It's crucial to master this form as it's the gateway to many advanced grammar points.
The te-form is a conjugated form of a verb that always ends in either て (te) or で (de). Its primary purpose is to connect clauses, similar to using "and," "then," or "after" in English, but with a nuanced sense of sequence or cause-and-effect. It indicates that one action happens before another. The final verb in the sentence determines the tense.
Example:
Forming the te-form depends entirely on the verb group. Let's break down the rules for each group with detailed explanations and examples:
Godan verbs are identified by the fact that their dictionary form (the form ending in -u) changes before the -masu ending. They require a bit more memorization. Think of it like this: the ending of the dictionary form dictates the te-form ending.
う, つ, る → って (-tte)
む, ぶ, ぬ → んで (-nde)
く → いて (-ite)
かく (to write) → かいて (kaite) - writing
きく (to listen) → きいて (kiite) - listening
Exception: いく (to go) → いって (itte)
ぐ → いで (-ide)
す → して (-shite)
Important Note about Small tsu (っ): When the te-form ends in tte, you might notice a small tsu (っ). This represents a doubled consonant and creates a slight pause, similar to a glottal stop.
Ichidan verbs are the easiest! They always end in -iru or -eru, and the te-form is formed by simply removing the -ru and adding -te.
There are only two irregular verbs, so memorize these!
Now that you know how to form the te-form, let's see how to use it to link actions. The basic structure is:
(Verb in te-form) + (Verb in plain form (present/past))
The first verb is in the te-form, and it describes the action that happens first. The second verb is in the plain form (either present or past), and it describes the action that happens after the first action. The tense of the entire sentence is determined by the tense of the last verb.
Examples:
うちにかえって、シャワーをあびます。
きっさてんにいって、コーヒーをのみました。
ほんをよんで、ねました。
あさごはんをたべて、がっこうへいきます。
Order Matters!
The order of the verbs in the te-form sequence reflects the actual sequence of events. The first action must logically happen before the second action.
Example of Incorrect Usage (to illustrate the point):
コーヒーを飲んで、喫茶店に行きました。(Incorrect) Koohii o nonde, kissaten ni ikimashita. (I drank coffee and went to the cafe.)
If said in this manner, it implies that you drank the coffee before going to the cafe, which doesn't make much sense.
Reasoning with the te-form:
The te-form can also imply a cause-and-effect relationship, although this is subtle at this point.
Convert the following verbs to their te-form. Remember to consider the verb group!
Now, create sentences using the te-form to link the following actions. Use the past tense for the final verb.
Let's explore a wider variety of sentences using the te-form to solidify your understanding:
シャワーをあびて、かいしゃへいきます。
コーヒーをかって、ともだちにあいました。
てがみをよんで、へんじをかきました。
でんしゃにのって、しごとへいきます。
レストランでばんごはんをたべて、ホテルへかえります。
ともだちのいえに行って、テレビを見ました。
Using the te-form with particles: Remember to include any necessary particles before the te-form verb.
