I never noticed that UK people say "absolutely" a lot. Generally, I'm enchanted by their speech patterns with the rare exceptions including:
- using the hard a sound in pasta, mall, etc.
- using the hard a sound in Barack AND putting the emphasis incorrectly on the second syllable.
But hey, they invented the language, they can do what they like with it.
Have you noticed the American media has adopted the cringe-worthy term "baby bump" (for a pregnant woman who is showing)? Awful. If we want to borrow from the Brits, it should be the aethestically pleasing British spellings.
