行為
こうい
koui
The word "kōi" refers to a conscious act or deed, typically viewed from an objective, legal, or ethical perspective. It is significantly more formal and abstract than "kōdō" (行動), which describes general behavior or the physical act of moving/acting. While "kōdō" is used for everyday actions (e.g., "taking action to solve a problem"), "kōi" is used when the action is being judged as right or wrong, legal or illegal.
In legal contexts, it specifically refers to an "act" that can be subject to liability or a crime. In philosophical or religious contexts, it refers to a "deed" that reflects one's will or morality.
Avoid using "kōi" for simple, routine physical movements. For example, calling the act of brushing your teeth a "kōi" would sound unnaturally clinical or overly dramatic, as if the act of brushing teeth were being analyzed in a court of law or a moral treatise.
Meanings
A conscious action or deed, often discussed in legal, ethical, or philosophical contexts.
