Hello Hana!

In creating a sentence or in talking to someone you need to choose the right words in describing your ideas. Also you need to compose a sentence that is clear and accurate. One more thing you need to omit some word that is not included or those words you used in other sentence. Try to find synonyms of that word and you can use it.
