大马 is a colloquial abbreviation for
马来西亚 (Mǎláixīyà, Malaysia), used widely by Malaysian Chinese (
大马华人) and in Singapore-Malaysia regional media. The
大 ('big') distinguishes it from
西马 (xīmǎ, West Malaysia) and
东马 (dōngmǎ, East Malaysia/Borneo). Mainland speakers usually use the full
马来西亚 instead.
