Introduction to Japanese Verb Tenses

Learning a new language can be both a thrilling and challenging endeavor. Japanese, in particular, has a unique structure and set of grammatical rules that can seem daunting at first. One of the most fundamental aspects of mastering Japanese is understanding its verb tenses. Unlike English, where we have various tenses such as past, present, and future, Japanese verb tenses operate a bit differently. In this article, we’ll delve into the essentials of Japanese verb tenses to help you get a solid grasp on how they work.

Basic Verb Forms

Before we dive into the tenses, it’s crucial to understand that Japanese verbs primarily fall into three categories:

1. **Godan (五段) or Group I Verbs:** These verbs end in -u, -tsu, -ru, -mu, -nu, -bu, -ku, -gu, or -su. Examples include 書く (kaku – to write) and 話す (hanasu – to speak).
2. **Ichidan (一段) or Group II Verbs:** These verbs end in -iru or -eru. Examples include 食べる (taberu – to eat) and 見る (miru – to see).
3. **Irregular Verbs:** There are only two primary irregular verbs in Japanese: する (suru – to do) and 来る (kuru – to come).

Dictionary Form (辞書形)

The dictionary form, also known as the plain form, is the form of the verb that you would find in a dictionary. For example, the dictionary form of “to eat” is 食べる (taberu), and “to write” is 書く (kaku).

Present/Future Tense

Japanese does not differentiate between the present and future tenses in the same way that English does. Instead, the context usually clarifies whether an action is happening now or will happen in the future.

Godan Verbs: To form the present/future tense of Godan verbs, you change the final -u to -imasu for the polite form and leave it as-is for the plain form.
– 書く (kaku – to write) becomes 書きます (kakimasu) in the polite form.

Ichidan Verbs: For Ichidan verbs, you drop the -ru and add -masu for the polite form.
– 食べる (taberu – to eat) becomes 食べます (tabemasu) in the polite form.

Irregular Verbs:
– する (suru – to do) becomes します (shimasu) in the polite form.
– 来る (kuru – to come) becomes 来ます (kimasu) in the polite form.

Past Tense

The past tense in Japanese is formed by modifying the verb ending. Here’s how you do it for each verb category:

Godan Verbs: The past tense is formed by changing the final -u sound to its corresponding -ta form.
– 書く (kaku) becomes 書いた (kaita) in the plain form and 書きました (kakimashita) in the polite form.

Ichidan Verbs: For Ichidan verbs, you drop the -ru and add -ta for the plain form and -mashita for the polite form.
– 食べる (taberu) becomes 食べた (tabeta) in the plain form and 食べました (tabemashita) in the polite form.

Irregular Verbs:
– する (suru) becomes した (shita) in the plain form and しました (shimashita) in the polite form.
– 来る (kuru) becomes 来た (kita) in the plain form and 来ました (kimashita) in the polite form.

Negative Forms

Understanding how to make verbs negative is essential for expressing things you don’t do or didn’t do.

Present/Future Negative:
– Godan Verbs: Change the -u to -anai for the plain form and -imasen for the polite form.
– 書く (kaku) becomes 書かない (kakanai) in the plain form and 書きません (kakimasen) in the polite form.
– Ichidan Verbs: Drop the -ru and add -nai for the plain form and -masen for the polite form.
– 食べる (taberu) becomes 食べない (tabenai) in the plain form and 食べません (tabemasen) in the polite form.
– Irregular Verbs:
– する (suru) becomes しない (shinai) in the plain form and しません (shimasen) in the polite form.
– 来る (kuru) becomes 来ない (konai) in the plain form and 来ません (kimasen) in the polite form.

– Ichidan Verbs: Drop the -ru and add -nakatta for the plain form and -masen deshita for the polite form.

– 来る (kuru) becomes 来なかった (konakatta) in the plain form and 来ませんでした (kimasen deshita) in the polite form.

Te-Form (て形)

The te-form is incredibly versatile and is used in a variety of grammatical constructions, such as making requests, connecting sentences, and forming progressive tenses.

Godan Verbs: The te-form varies depending on the ending of the verb:
– Verbs ending in -u, -tsu, -ru: Change to -tte.

Progressive/Continuous Tense

The progressive or continuous tense in Japanese is formed by combining the te-form of a verb with the auxiliary verb いる (iru).
