限于

限于 means 'limited to' or 'restricted to,' often used to indicate a boundary or constraint in scope, time, or capacity.

限 (xiàn) originally meant 'limit' or 'bound,' and 于 (yú) is a classical preposition meaning 'to' or 'in.' Together, they form a phrase indicating a restriction or limitation placed on something.

限于 is commonly used in formal or written contexts to specify boundaries, such as in legal documents, official statements, or academic writing. It can also appear in everyday speech when someone wants to emphasize the limits of an action, statement, or situation.
