Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
For a closed metal food container, “can” is standard in US English and also used in UK English, while “tin” is a common UK term. “Tin” also names the metal itself and other lidded containers, so the words are only equivalent in the relevant container sense.
“Corn” and “maize” overlap in the crop sense, especially across US and UK usage, but they are not interchangeable in every sense. US “corn” commonly means maize; UK “corn” can be a broader cereal-grain term, so regional and sense context matters.
Use the regional term your audience expects: “tea towel” in UK usage and “dish towel/dishtowel” in US usage. This comparison is limited to the dish-drying-cloth sense; household textiles can have overlapping local names.
In common UK usage, the “ground floor” is at street level and the “first floor” is one level above; in US usage, “first floor” commonly means the street-level floor. This is a regional numbering convention, not a claim that every building or local system uses identical labels.
For a self-contained home within a larger building, “flat” is the usual UK term and “apartment” is especially common in US English. The equivalence applies to the dwelling sense only; both words have additional meanings, and “apartments” also has a distinct formal-room sense in some British contexts.
“Gearshift” and “gear lever” can name the same vehicle control, with Cambridge marking “gearshift” as US and “gear lever” as UK. The page keeps the comparison regional rather than treating either term as universally wrong.
