无理(無理)wúlǐ(wu2li3)

Cultural note

In Chinese culture, the concept of reason and logic is highly valued, especially in legal and social discussions. The term 无理 may often be used to critique behavior that disregards social norms or common sense.

Memory tip

Imagine a 'wolf' (the '无' sounds like 'wu', which you can picture as a wild wolf) howling at the moon without any logical reason ('理') behind its actions. The image of a wolf acting irrationally helps connect the sound of the word with its meaning.
