On Line vs. In Line vs. In A/The Queue
Hello everybody! 856pm here with regionalistic differences. This is in English because only fluent speakers would care about this trivial nonsense. Note that I'm talking about lines (queues) of people, not the internet. Some people say, "I'll stand on line," and some say "in line," and others say "in queue." So, which is right? It depends on where you are. Generally, if you're in the vicinity of New York City, you should say "on line." In the rest of America, say "in line." In Britain, say "queueing" or "in a/the queue." If in doubt, say "in line," unless you want people to think you're British or a New Yorker.
I didn't know that, thanks! :) Hungarians are usually taught British English, but for our misfortune, American English often pours into our English knowledge creating an mixture of British-American English... For the record, I hadn't even heard of "on line" before I read your post...
