Actually, it's apparent that Colin's comments were transcribed by an Englishman; beyond that, it's as perfectly acceptable to say "learnt" (for "learned")as it is to say "dealt" (for dealed). More properly, one IS "learned" (pronounced "ler-ned", an adjective), and one HAS "learnt" ("lernt", past tense of learned ("lernd"), a verb)). As has always been true, current usage defines correctness, and that correctness depends, to a large extent, upon one's location. Now, where's my Fuller's ESB?
