In the US, we spell practice with a "c" whether it is a noun or a verb. Advice/advice and who's/whose are tricky though, especially for people who speak English as a second language (though it seems most Americans have trouble with it as well). Here are some more that people mix up: its/it's "its" is possessive and refers to ownership: "The cat licked its tail. "it's" is a contraction short for "it is": It's getting dark outside, so come in the house to/too/two "to" can be used a couple of ways. One is in the place of the word "toward", such as "Go to the other side of the room." Another usage is verbs in the infinitive form: to work, to play, to sleep, to do, etc. "too" also has a couple of uses. I can mean "also": "I have blue eyes too!" Or it can mean "excessively": "You talk too much!", "It is too hot outside to wear long pants." "two" is the number after one! "I have two feet." your/you're This is one of my pet peeves! Get it right people! "Your" is a possessive adverb that refers to ownership: "I like your ice cream better than Bethany's." "You're" is a contraction of the words "you are": You're starting to make me angry with your bad grammar! There you go... hope I helped clear some things up for you!

You look quite confused. I have to say something about repeated confusion.If you find the same confusion many times you need a book.Do not ask other. You can enjoy asking .That's your freedom. It is better to buy a standard dictionary.
