完美 (wán měi) is an adjective meaning 'perfect' — describing something that is flawless, complete, and ideal in every way. The character 完 means 'complete' or 'entire', while 美 means 'beautiful' or 'excellent'; together, they convey the idea of completeness combined with beauty or excellence. It emphasizes both structural wholeness and aesthetic or functional superiority.

This word is commonly used to praise outcomes, appearances, performances, relationships, or plans — for example, a perfectly executed dance routine, an impeccably dressed person, or a flawlessly organized event. While positive and widely understood, 完美 carries a strong, sometimes elevated tone; it's rarely used for everyday objects unless emphasizing exceptional quality. It’s also central in expressions like 完美主义 (perfectionism), highlighting cultural awareness of high standards.
