The kanji 闘闘 is a 会意形 (かいいけい - combined meaning) character. It is formed from the components: ⚫︎　"門" (もん - mon): gate ⚫︎　"士" (し - shi): samurai, warrior ⚫︎　"寸" (すん - sun): a unit of measure, which also implies the meaning of "to push" or "to strike." The original form depicted warriors (士) inside of a gate (門), indicating a struggle or fight taking place. The "寸" component was added to emphasize the action of pushing or fighting. This combination conveys the sense of warriors battling within a restricted space or confined area. Over time, the character evolved to represent the broader concept of fighting and competition.
