Translation guide
The English word "adversary" refers to an opponent or enemy, often in a formal, competitive, or conflict context. In Japanese, the most natural translation depends on the type of opposition: a rival in sports or games, an enemy in battle, a legal opponent, or a more abstract foe. This guide helps you choose the right word for each situation.
