'伪命题' (wěimìngtí) literally means 'false proposition' — composed of 伪 (wěi, 'fake' or 'spurious'), 命 (mìng, from 'proposition' or 'thesis', as in 命题), and 题 (tí, 'topic' or 'question'). It refers to a question or statement that appears meaningful but is actually logically flawed, based on false assumptions, or unanswerable because it misrepresents reality. Such questions often arise in philosophical debates, online arguments, or everyday reasoning — for example, asking 'Which came first, the chicken or the egg?' when discussing evolution ignores that species evolve gradually, making the dichotomy itself invalid.

This term carries a critical, analytical tone and is commonly used in academic, journalistic, or intellectual discourse to dismiss arguments that are ill-posed or rooted in faulty premises. It’s not about factual inaccuracy alone, but about conceptual emptiness: the question cannot be meaningfully answered without first rejecting its underlying framework.
