Question

We should practise games every day.



why do we use practice not practise????????????

Answer 1

here practice is a noun and practise is a verb and in that sentence we need to add a verb not a noun so we need to write practise there
example sentences:
*you need more practice
*you should practise more.

Answer 2

You need more practice. 
("practice" - noun)
 "You need more preparation." This sounds okay.
 Therefore, practice is correct.)

You should practise more. 
("practise" – verb)
( "You should prepare more." This sounds okay.
 Therefore, practise is correct.)
This is because practice is a noun, but practise is a verb.
