Two spelling same meaning . Which one

[drinkingwineoutofamug]

Recognise or recognize
It's for my assignment.

Recognise

The first. The second is American English.

S if you are in the UK.

Z is more American English I believe.

Recognise if you are in the UK, recognize if you are in the US.

Yes, s if in the UK. Z if you are in the US.

Bloody hell that was quick. Thank you people. Google confused me as it said both.
My academic writing is pants and I want to get at least a merit on my diploma so I may be back

In that case buy a good Oxford English Dictionary. I still have mine from university.

Google will often say both now for s/z spellings which is infuriating as a parent. Don't get me started on school using "sulfur" for sulphur.

I used to listen to Grammar Girl podcast about the different spellings or phrases that people use. Very interesting.

Also check your spellchecker is set to UK English not US English.

Surely recognize was the original English spelling that we exported to the American colonies way back when?

They kept it that way, we changed it to be consistent with words like surprise.
I use recognise if I'm writing for an organisation where I know their house style requires it, and recognize when I have control over the finished piece.

The OED explains it well, but it's basically to do with whether the origin is Latin or Greek, I think.

I think leonardthelenming is right. Z is older English and American.

Both spellings are OK, but why would you use Google to check this sort of thing? It's an American company.

@leonardthelemming -ize comes from the original Greek, -ise comes via French. The -ise spelling is used more commonly in British English than -ize so unless there is a style guide that specifies otherwise it is probably safer OP sticks with -ise as the default.

Also OP, it is important to be consistent. For example, if you use recognise, you should use analyse/finalise/normalise etc and vice versa recognize/analyze/finalize/normalize.

Z is used in Oxford, according to my DF, who was brought up there. I use S.

@PhilomenaChristmasPie The University of Oxford style guide uses -ise, whereas the OUP uses -ize.

S is generally used in UK English for consistency but if the word has a Greek root it should really be a Z.

Sulfur is the fault of IUPAC trying to nail down naming conventions. British English users agreed to use "sulfur" and American English users were supposed to switch from "aluminum" to "aluminium", but half the time they don't.
