Indian English follows British conventions in most respects — spelling, dates, and much vocabulary. Knowing where American English differs matters if you write for American clients.

Spelling patterns

  • -our / -or: colour / color, favour / favor, behaviour / behavior
  • -ise / -ize: organise / organize, realise / realize
  • -re / -er: centre / center, metre / meter
  • -ce / -se: licence / license, defence / defense
  • Double l: travelled / traveled, cancelled / canceled

Everyday vocabulary

  • flat / apartment
  • lift / elevator
  • lorry / truck
  • petrol / gas
  • queue / line
  • rubbish / trash
  • holiday / vacation
  • mobile / cell phone
  • CV / resume
  • timetable / schedule
  • ground floor / first floor

That last one causes genuine confusion. The British ground floor is the American first floor.

Dates

  • British: 14/08/2026 — "the fourteenth of August"
  • American: 08/14/2026 — "August fourteenth"

Grammar differences

  • British favours the present perfect: "I've just eaten." American often uses the past simple: "I just ate."
  • Collective nouns: British "the team are playing well", American "the team is playing well"
  • "at the weekend" (British) / "on the weekend" (American)
  • "got" (British past participle) / "gotten" (American)

Which should you use?

Whichever your audience uses. What matters far more is consistency — "colour" and "organize" in the same document looks like carelessness rather than choice.

Set your word processor's language to match your audience and let it catch the mixing for you.
