“America” can mean the whole continents—North America and South America together. So it’s like the big landmass with tons of countries. But most people, especially in casual talk, use “America” to mean just the United States.

Saying “America” instead of “the United States” isn’t usually offensive, but some folks from other countries in the Americas might roll their eyes because it feels like the US is claiming the whole continent’s name for itself. It’s kinda like calling yourself “the world” when you’re just one part of it.

But honestly, in everyday conversation, calling the US “America” is super common and most people don’t get salty about it. Just depends on who you’re talking to!
