Notes on Usage

• "Trẩu" is a specialized noun. It should not be confused with the informal, derogatory slang term "trẩu" or "trẩu tre," which describes a rustic, unsophisticated, or tacky style. That slang term is homophonous but semantically distinct and is considered colloquial or subcultural. This entry defines the standard botanical term.
