Can是英语中的多功能词汇，具有情态动词与名词双重词性，发音为英[kæn; kən]、美[kæn; kən]。其词源可追溯至古英语“cunnan”，原意为“知道、有能力” [1]。
作为情态动词，Can主要表达能力（如“能/会”）、许可（如“可以”）、请求、可能性（如“可能”）及推测等功能 [3-4] [6]。名词形式指金属或塑料容器（如“罐/听”），并衍生出厕所、监狱等俚语含义 [2-3]。动词形态涵盖罐装保存、解雇等动作。部分短语如“can be”“how can”在口语中高频使用。
该词演变自古英语，逐渐分化为情态动词与容器名词两大核心义项 [1]。美式英语中“can”对应英式“tin”的容器表述，同时衍生出核工业术语等专业用法。其语义网络通过语言实践扩展，覆盖日常交流及特定领域 [2] [5]。
