+

+
+**Note:** Both American and British English are accepted in IELTS, but consistency improves clarity and avoids confusion.
+
+
+1. -our vs -or
+
+BrE: colour, favour, honour
+
+AmE: color, favor, honor
+
+Rule: British English keeps the “u” in many words ending with -our.
+
+2. -re vs -er
+
+BrE: centre, metre, litre
+
+AmE: center, meter, liter
+
+Rule: British English usually uses -re; American English switches to -er.
+
+3. -ise vs -ize
+
+BrE: realise, organise, recognise
+
+AmE: realize, organize, recognize
+
+Note: Both spellings exist in BrE, but -ise is more common in the UK; AmE prefers -ize.
+
+4. -ll vs -l in verbs
+
+BrE: travelled, labelled, cancelling
+
+AmE: traveled, labeled, canceling
+
+Rule: British doubles the consonant in some verb forms; American does not.
+
+5. -ogue vs -og
+
+BrE: dialogue, catalogue, analogue
+
+AmE: dialog, catalog, analog
+
+6. -ce vs -se
+
+BrE: defence, licence (noun)

+Tip: In BrE, “license” is the verb; “licence” is the noun. AmE uses “license” for both.
