Both words relate to limits, and Chinese learners often confuse them. Limit means a specific maximum or minimum value, often a number, as in speed limit. Limitation means a restricting rule, fact, or weakness, often used in the plural to list shortcomings.

这两个词都与“限制”有关，容易被中国学习者混淆：limit 强调具体的最大值或界限，常与数字搭配；limitation 强调造成局限的规则、事实或缺陷，常用复数列举不足之处。此处不比较 limit 作动词“限制”的用法。
