Plain form (casual speech) — 食べる, 行く

JLPT N4 Plain Forms

The dictionary form used with friends and to build advanced grammar

The plain form (also called dictionary or casual form) is how Japanese is really spoken among friends and family — 食べる instead of 食べます, 行く instead of 行きます. Beyond casual chat, it's the base that dozens of N4+ patterns attach to (〜と思う, 〜つもり, 〜たら…), so learning it doubles as unlocking everything that follows.

How to form it

PatternExample
る-verbs = dictionary form食べます → 食べる — eat
う-verbs = dictionary form行きます → 行く / 飲みます → 飲む
Irregularsします → する / 来ます → 来る(くる)

Watch out

Casual form isn't “broken” Japanese — it's the correct register for close relationships, but using it with strangers or superiors sounds rude. When in doubt with someone new, stay in 〜ます. Grammar books call this the “dictionary form” because it's how verbs are listed.
