apologise
as in "I apologise profusely for the spelling error on our meeting agenda."
co-ordinator
this is just plain annoying. an unnecessarily hyphenated word. i've held a few jobs in the past where my official title included the word "Coordinator," but when a British HR department reads my resume they think I've misspelled part of my own job title. as if.
colour
i rather like this one. no complaints ;-)
disorientated
sounds more like a George W. Bush-ism than an actual word.
favour
meh.
manoeuvre
talk about over-complicating something...
organisation
this is one i've had to write or type quite a few times, and each time i do, i roll my eyes. what do the Brits have against the letter Z anyway?
programme
again, over-complication.
tonne
not that i often ever refer to a ton of anything - but again, it's just extra letters that bring nothing to the party. then again, i also dislike the metric system in general, so whatever.
There you have it: a little warm-up, which was certainly not exciting, but perhaps interesting.
