Practice or practise?
These words are frequently confused by people. They sound the same but have a different purpose: practice is a noun and practise is a verb. In American spelling there is no difference. They use practice as both noun and verb.
Musicians attend rehearsals to practise their music. (Here it is the action of repeating the playing of music to improve.)
I’m going to music practice. (Here it is the name of the activity.)
