How to Write 困 (kùn) — Meaning “Sleepy / Trapped”

Imagine a tree (木) trapped inside a square box (囗), feeling sleepy because it cannot move. This mental image links the enclosure to both meanings: the tree is trapped, and being stuck makes it sleepy.

Write the outer enclosure 囗 first, starting with the left vertical line, then top horizontal, right vertical, and close with the bottom horizontal. Inside, the tree 木 must be centered and not touch the outer box; a common mistake is making the bottom stroke of 囗 too short, causing the box to look open.

困 contains a tree (木) inside the enclosure, meaning sleepy or trapped. 囚 has a person (人) inside, meaning prisoner, and 四 is a number with a different inner shape (a simplified 儿 or two strokes). Focus on the inner component: wood, person, or number strokes to distinguish them.

困 is very common in daily life: say 困了 (kùn le) when you feel tired and ready to sleep, or use 困难 (kùn nán) to describe a difficult problem. The character also appears in 困境 (kùn jìng) for a dilemma, showing its core idea of being stuck or constrained.

Common words containing 困 include: 困难 (kùn nán) — Difficulty / Hard; 困了 (kùn le) — Sleepy; 困境 (kùn jìng) — Dilemma / Predicament.
