Re. Catalyzer vs. Catalyser. We're a confused lot here in Canada where both UK and US spellings are acceptable, many of us swayed by our heritage or the literature/media we're most exposed to. Legal stuff uses what is referred to as the Queen's English (UK) as we're still ruled by Her Majesty Liz, and for federal documents it's immediately followed by a matching translation in French as we're officially bilingual, and it's French Canadian, not Parisian French, which is the only official language in the province of Quebec. People like me need to load both US and UK dictionaries for our spell checkers so we can swing either way depending on our mood, and if you're a federal government employee also a French Canadian dictionary. One thing Canadians universally agree on is it's Aluminum, not Aluminium. And don't get me started on metric, vs. US vs. Imperial measurements, where almost all are used here while metric is the only official one. When someone says their gas mileage is 30 mpg, we never know whether that's US or Imperial gallons, and if you start talking mileage in the official litres per 100 kilometeres my brain no longer functions. I'm just glad we don't have our speedometers in furlongs per hour, curb weights in stone and gas pumps dispensing in cubits.
