Practise / Practice
In many parts of the English speaking world (UK, Ireland, Australia, Canada, and South Africa) “practice” is the noun, “practise” the verb. However, in the U.S.A the spelling “practice” is more often used for both the noun and the verb. Contrary to popular belief a significant minority of the American population also observe the distinction. If you are not sure about what a verb or noun is, it might be safer to just use the spelling "practice", as many Americans do!

"Affect" and "effect" are two words which have a similar or identical pronunciation in spoken English, but have different meanings when used correctly in written English. "Affect' is most commonly used as a verb and means "to influence or change" or "arouse feelings". The word "affect" is rarely used as a noun and when it is it is in a fairly narrow field of psychology in connection with emotional states. In contrast to "affect", the word "effect" is most often used as a noun. "Effect" as a noun means "a result". "Effect" is rarely used as a verb and means to make something happen.
