While I am writing articles, I am confused while placing these two words. :huh:
According to me, 'practice' is noun and 'practise' is verb.

But my Microsoft word shows errors and if they are used interchanged, it is not showing errors.
I or Microsoft word, who is correct?

I agree that 'practise' is verb and 'practice' is noun. But this is British English. Microsoft follows American English.

You needn't be this much worried or confused about the spelling styles of British and US English. Both are equaly accepted although the latter has got a little more edge in the modern world. Still, most of the Indians follow British English. If you are confident that the spelling of any word you type is correct either in the British style or in the US style, go forward and left away the confusion. What's important is the stuff with correct grammar with alluring presentation.

Both are correct as practice comes basically from Latin collection. Like I am used to writing Labour, colour etc but US dictionary rejects them If I write for English sites I have to according to English version.

When you are writing for US sites, are you following American dictionary?
