Mouth

N5 · 3 stroke · 20 kanji

An open mouth, ready to speak. Three strokes form the three walls of lips — left, right, and bottom.

▶Learn Mouth through story

Look at the shape: three lines forming an open square, open at the top. That is a mouth, wide open. Every word you speak, every sound you make, every name you call — all of it passes through 口. It is the most fundamental communication radical in Japanese.
