I have often seen initialised in lots of text, but when I want to write it in Microsoft office word, it says it was misspelled and it should be initialized instead of initialised.
so here is my question:
Which one of them is the correct spelling?
and if both of them are correct, when I should use one or the other? Is there any rule regarding this?
Additional note: when I was writing this post, it would give me a spelling error notice each time I wrote initialised.
