While sharing language and historical roots, the UK and U.S. diverge notably:
| Aspect | British | American |
|---|---|---|

| Government | Constitutional monarchy; PM + Cabinet from Parliament; unwritten constitution. | Federal republic; President (head of state/govt); written Constitution; separation of powers. |
| Class | Historically stratified (upper/middle/working); accents, education signal class. | More fluid "middle-class" self-ID; wealth/income primary markers. |
| Manners | Queuing sacrosanct; "please/thank you/sorry" frequent; indirect communication. | Queuing respected but less ritualized; directness valued; "sorry" less reflexive. |
| Humor | Dry, self-deprecating, irony, understatement. | Broader, observational, exaggeration, sarcasm. |
Both are diverse, evolving cultures—these are broad strokes, not absolutes.
