Searching for the right word doesn't always mean you find it. You might choose a word that looks or sounds similar but doesn't have the same definition. For example, the word "loose" means something isn't tight, while "lose" means to misplace something.

Commas are used to separate and group ideas. However, you may not need a comma even though there are multiple ideas in a sentence.
