[this should have been posted last night, so probably out of date now... responding to something about someone not liking American, and then someone else being incredulous about them not liking an "entire language", IIRC. Something like that.]
Entire
dialect, mabye. I don't know if I'd go to the extent of "how it sounds" (after all, US accents, of all kinds, are too all-pervasive in UK media (film, TV, 'even' radio[1]) to sometimes even consciously
perceive them as foreign, in the heat of the moment) but I tend to pull up short when reading things
written in the 'Merkin manner. "Color", "center", "(schedule/television) program", "(length of) meter", "sulfur", etc, etc...
However, I'm fairly sure you lot over there think the same about "colour", "centre", "programme", "metre" and "sulphur".
(Strangely, I don't mind a "computer program" or an "electricity meter"[2]. So it's quite possible that my condition is psychosomatic and depends on me being conscious of the context!)
[1] Though not so much "import" stuff, since the mid-20thC fad for emulating US dis[kc]-jockeys There's a few regularly-heard voices that are 'over here' helping out with various dramatisations of various US novels, plus 'American character actors' in various British sit-coms, of course including Jay Tarses and others who may or may not actually be American (I suspect none of the others are, even those playing the
colonists[3]) in "Revolting People", the sitcom
about pre-/during-/post-Revolutionary America in Jay's native Baltimore.
[2] Was going to say "gas meter", but I can't bring to mind what you'd say for that, given you've co-opted "gas(oline)" as the term for what we call "petrol(eum)". So, you see, there's still plenty of mystery, here in the UK, about the everyday lives of you rebellious colonials, despite kindly shipping us entertaining program(mes) like House, with actor Hugh Laurie and The Wire with Dominic West, to mention just two of your finest American actors...
[3] Mind you, their real-life counterparts may probably have had something more of a (UK) West Country accent, or thereabouts, at that time.
