Criteria are particular things you look for when you judge something and make a decision. Criteria are like little tests. For example, if someone wants to buy a computer, they don't usually buy just any computer. They choose based on certain things. These things are their criteria. They might decide that the computer must be under a certain price. It must have a certain amount of memory. It must have a certain speed, and it must look good and be of the right size. If a computer passes all these criteria, then they judge that it is what they are looking for. "Criteria" is a plural noun. The singular form is "criterion." |
