plain form（verbs）

So far, you have learned the “ない form” in Lesson 7, the “た form” in Lesson 8, and now in this Lesson 9, we’re learning the “dictionary form.”

These, the “dictionary form,” the “ない form,” the “た form,” and the “negative past form(なかった form),” are collectively referred to as the “plain form” of verbs. Let’s organize them once.

Example: 食べます (eat)

ます/ですform is used in formal situations, while plain form is used in casual situations.

Next is the なadj..

Example) 便利べんり(useful)

Next, let’s look at the case of nouns. This is the same as the なadjective.

Example) 晴れ (sunny)

まさとし
