包含 (bāo hán) is a transitive verb meaning 'to include' or 'to contain' — literally, 'to wrap up and hold within.' The first character 包 (bāo) means 'to wrap,' 'to enclose,' or 'to cover,' while 含 (hán) means 'to hold in the mouth,' 'to contain,' or 'to imply.' Together, they convey the idea of something being fully enclosed or incorporated within a larger whole. It’s commonly used in formal, academic, or descriptive contexts — for example, when listing components of a system, describing features of a product, or stating what a concept encompasses.

This word emphasizes completeness and intentional inclusion: if something 包含 X, then X is an explicit, integral part of it — not merely present by coincidence. It often appears after a subject noun and before a noun phrase (e.g., 'The course 包含 three modules'). Unlike colloquial alternatives like 有 (yǒu), 包含 carries a more precise, structured connotation and is rarely used in casual speech about everyday objects unless emphasizing composition or scope.
