It's also another name for a battery
Fail. Battery = multiple cells. It's called a cellphone because it operates on a cellular network ie made up of cells. They are called cells in the industry I believe.
And for you people complaining about the spelling, it's worth noting that there were no standardised spellings way back, and we just happened to standardise differently. Lots of spellings (including ize and ise) in use for many many years here.
And whoever it was complaining about soccer – you're making a fool out of yourself. There were many different games called football before the 19th century played all over. One day a group got together and standardised some rules, creating Association Football. Not the only kind of course, we also have Rugby Football and Gaelic Football. In Edwardian England the fashion was amongst young dandies to shorten words and put 'er' on the end, like 'badders' for Badminton and so on. Soc is a well known abbreviation for 'Society' or 'Association', which is where we get 'soccer' from. In public schools where both games were played, you get rugger for Rugby and soccer for Association football.
The word is as English as cream teas I'm afraid. That's tea from the far East, you understand.
Incidentally, my wife is American and she uses a lot of words that to us seem really old fashioned English. She calls wellies 'galoshes' for instance.
