I’m an American living abroad (with a minor in linguistics).
Another EE with an interest in linguistics? What are the odds?
And it just gets ridiculous that 100% of soldering videos by Americans have half the comments from angry Brits complaining about the pronunciation, the usual argument being “lazy Americans, it has an L, so you must pronounce the L!!!!”
When I first heard the American pronunciation of solder I found it as strange as listening to "Hermione" for the first time in
Harry Potter and the Philosopher's Stone.
Given the polemic, I decided to investigate. Now I can accept the American version without reservations.
The main mistake you, like most people, make is to essentially assume that British English stayed the same, while American English changed a lot. But why would English in Britain remain unchanged for 400 years? It didn’t. In fact, it changed more than American English did!! (French had the same thing with Quebec: the French in their former colony changed less than the French in the homeland!) When Hollywood makes a movie set in the middle ages and everyone is speaking something similar to the Queen’s English, it’s completely wrong — language historians say that it should sound much more like American English. whether the movie takes place in the New World or in medieval England.
The other British colonies were colonized in a much more ongoing fashion: they had settlers coming in from Britain until much later. Their closer ties to the homeland meant more pollination by modern British English. (Canada is a great example of this, having the same roots as American English, but with the continued British influence. So you get much the same foundation as American English, but with some distinctly more-British sounding pronunciations on a few words, e.g. “again”.)
You bet your bottom dollar that the same thing happened to other New World languages (Portuguese, Spanish, Dutch).
Like in the English case, things get really worse when these ex-colonies start to produce content (books, music, videos, films, etc.) using all those (in the current perspective of the ex-metropolises) "archaic", "regional" or "less prestigious" features and "invade" their ex-metropolises.
The accusations of ruining their once pure and heroic idiom abound.
Makes me wanna say: next time you feel the urge to colonize a distant land, don't.
