Totum pro parte

Some place names of large areas are commonly used to refer synonymously to a smaller part of the larger area than is strictly deemed correct. Examples of this include:

• "America" for the United States (see use of the word American)
• "Asia" for East and Southeast Asia (conversely, Asia is a pars pro toto, originally referring only to Asia Minor)
• "China" for the People's Republic of China since the 1970s, and prior to that, the Republic of China
• "The Congo" for the Republic of the Congo or the Democratic Republic of the Congo
• "Europe" for the European Union or for Continental Europe excluding the British Isles
• "Germany" was often used for West Germany during the Cold War
• "Ireland" for the Republic of Ireland excluding Northern Ireland
• "Korea" for South Korea, excluding North Korea
• "Macedonia" for the Republic of North Macedonia (see Macedonia naming dispute)
• "Micronesia" for the Federated States of Micronesia
• Nanyang, Maritime Southeast Asia, Malay Archipelago, Sunda Islands for Indonesia
• "Ulster" for Northern Ireland
• "Western Hemisphere" for the Americas
• "Yemen" was often used for North Yemen
• "Northumbria" for North East England or historic Northumberland and County Durham

The capital city of a country is often used to refer to the national government of the country.

• "Washington, DC", "Washington", or "DC" are often used to refer to the United States government.
• "Kyiv" to refer to the Ukrainian government.
• "London" to refer to the British government.

Similar to capital cities, the name of a city can be used to refer to the headquarters of intergovernmental organizations. Notable examples include:

• "New York" to refer to the headquarters of the United Nations, or the United Nations more generally.
• "The Hague" can refer to any of the international courts currently or formerly headquartered in The Hague. Most commonly it refers to the International Court of Justice or the International Criminal Court, which are often confused. Being "brought to the Hague" can refer to prosecution for war crimes more generally, often at the ICC.

The verb "to drink" is often used in this manner. Depending on context it can stand for the generic, standard definition "to consume a liquid" (e.g. "I'm thirsty, is there anything to drink?") or for the narrow, limited definition "to imbibe alcoholic beverages" (e.g. "He goes out to drink too often"). Also, fluid can be used for liquid, as in brake fluid or bodily fluid. (The presence of air, a fluid, is not wanted when there is low fluid.)
