I found it pleasant that an Indian friend (from Mumbai) used “Thrice” for “3 times”, a word I hadn’t heard since forever. Got me wondering if Indians who speak English as their first language use more traditional(?) English than the British these days?.
Anyway, 10 years ago I used to frequent waterski forums mostly used by Americans and ‘than’ was sometimes substituted with ‘then’, like “I’d rather have an X then a Y”. In recent times I’ve noticed it a lot more often on the internet in general, even occasionally on this forum. With the internet being mostly dominated by American Websites (Facebook, You Tube), Americanisms will dominate even more so then they did previously thru films, TV etc. Better get over it.
