葡萄牙 is the Chinese name for the European country Portugal. Though the characters 葡 (pú), 萄 (táo), and 牙 (yá) individually mean 'grape', 'vine', and 'tooth' or 'dental', respectively, they are used here purely phonetically — together they approximate the sound of 'Portugal' in Portuguese ('Portugal' → /puɾtuˈɡaɫ/ → pú táo yá). This is a common pattern in Chinese for transliterating foreign place names, especially those without direct semantic equivalents.

The term is exclusively used as a proper noun referring to the nation, its people, language, or culture. You’ll encounter it in contexts like geography, international relations, travel, sports (e.g., Portugal’s national football team), and food (e.g., Portuguese egg tarts, known as 葡式蛋挞 in Chinese). It is always written in full — never abbreviated — and functions identically to other country names like 法国 (France) or 日本 (Japan) in grammar and syntax.
