❓ FAQ
Should Indian students use British or American spelling?
Indian schools follow British English: colour, centre, organise, programme, travelled. Use British in exams! However, both are widely accepted in daily life and online communication.
Why are there two different spellings?
Noah Webster simplified American spelling in the early 1800s. He dropped U from -our words, changed -re to -er, and preferred -ize over -ise. British English kept the older French-influenced spellings.
Is -ISE or -IZE correct in British English?
Both are accepted in British English! Oxford University prefers -IZE (realize). Cambridge and most UK publishers prefer -ISE (realise). Indian schools accept both but lean towards -ISE.
What about online/informal writing?
Online, both are fine. Google, Microsoft, and most tech uses American spelling. Indian newspapers and textbooks use British. Be consistent — don’t mix systems in one document!
Does mixing British and American hurt exam marks?
It can! Using ‘color’ in one sentence and ‘centre’ in another shows inconsistency. Stick to one system throughout. For Indian exams, always use British spelling.
