Practice

Practice is the act of rehearsing a behaviour repeatedly, to help learn and eventually master a skill. The word derives from the Greek "πρακτική" (praktike), feminine of "πρακτικός" (praktikos), "fit for or concerned with action, practical", and that from the verb "πράσσω" (prasso), "to achieve, bring about, effect, accomplish".

In British English, practice is the noun and practise is the verb, but in American English it is now common for practice to be used both as a noun and a verb (see American and British English spelling differences; this article follows the British distinction).
