Sense: noun/1
'US' (with 'the' as 'the US') is the most common short form in news headlines and everyday speech. 'USA' (also with 'the') adds emphasis and is often used in international contexts, such as sports teams or formal documents. 'America' is the most casual and widely understood term, but it technically refers to the whole continent and can cause confusion. 'The United States' is the full formal name, used in official writing and speeches. 'The States' is an informal, friendly term common in travel conversation. Choose 'US' for neutral, everyday use; 'the United States' for formal writing; and 'America' for casual speech where the meaning is clear from context.

Etymology
The pronoun 'us' comes from Old English 'ūs', the dative and accusative form of 'wē' (we), tracing back to Proto-Germanic '*uns', and ultimately to Proto-Indo-European '*n̥s'. The abbreviation 'US' for 'United States' has a completely separate origin — it emerged in the late 18th century as an initialism of the country's name after the American Declaration of Independence (1776), becoming common in official documents and postal markings by the early 19th century. These two words are homographs: the same written form with unrelated historical roots.
