DIFFERENCES BETWEEN "practiCE" and "practiSE"

-Do not confuse "practice" with "practise". They sound the same and even look similar (except that one is spelled with a “c” and the other with a “s”) but their meanings are different. The word "practice" is a noun, it refers to an act itself, not who is doing it. On the other hand, practise is a verb meaning 'do something repeatedly to improve one skill'. It is a systematic training by multiple repetitions (rehearsing a behavior or engaging in an activity several times repeatedly) in order to improve or mastering that skill. To put this much simply, practise is a verb (doing word) and practice a noun (thing).
- It should be noted that in American English, both the noun and the verb are spelled "practice". Both forms are however used in the British English whereas the distinction is almost obsolete in the U.S. As a matter of fact, in other English speaking countries (Australia, Canada, UK, Ireland, and South Africa), "practice" is the noun and "practise" the verb. It is therefore important to make sure that use the right version for the right audience.
