鬪

It conveys actions involving conflict, struggle, or contest, such as physical fights, competitions, or disputes.

This phono-semantic compound character is formed by combining:

鬥 (tu, “to fight”) — representing the meaning, and

斲 (chak, “to carve or cut”) — representing the sound.

Originally, 鬪 was a simplified or variant form of 鬭 and 鬪, but 鬪 has become the most widely used.

There are many variant forms of this character—over 30 in total—including those from Simplified Chinese and Shinjitai (modern Japanese kanji forms). All characters that combine 門 (gate) with components like 斗, 豆, 㪷, 剅, 有, 鼓, etc., relate to the idea of "fight" and are considered variants of 싸울 투 (“to fight”).

Regional Usage:

Mainland China: Often replaces 鬪 with 斗 (which normally means "a measuring cup" or "to fight," depending on context) due to similar pronunciation.

Taiwan: Continues to use the traditional radical 鬥.

Japan: Uses 闘, a Shinjitai form where 鬥 is replaced with 門 (gate).

Hong Kong and Macau: Commonly use the traditional variant 鬭.
