Major vs Main: What’s the Difference?

Main points to the single most central thing — the main door, the main reason, the main character. There is usually only one ‘main’ in a group. Major is broader: there can be several major cities, major problems, or major causes, all important without one being the single center. Main answers ‘which one is central?’; major answers ‘how important is it?’. In practice: use main when singling out the top item, and major when marking high importance generally. (‘The main cause was engine failure, but there were two other major factors.’)
