Student or Learner
I am writing my first essay and I am wondering if I could use words like memorize, summarize or realize using -ze at the end.
I know that in UK it should be memorise, summarise and realise, but some UK dictionaries I have, and even dictionaries online, spell the words with -ze. Even word office 'tells' me that summarising is a mistake in English (United Kingdom) language and it should be summarizing.
I guess it changes from word to word, doesn't it?
I am a bit confused. What should I do?
If your copy of Microsoft Office is a US-based version, then it will tell you that "summarising" is wrong. However, "summarising" is correct in British English.
If you are writing an academic essay for a UK-based institution, I recommend you use the -ise ending wherever appropriate. Remember also to use, for example "favour (not favor)" and "colour (not color)".
The simple answer to what you should do is that you should decide between AmE and BrE and then stick to it.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
