necessary
This word is often used with the phrase "it is necessary to..." followed by a verb, which is a common way to express that something must be done. Be careful not to confuse "necessary" with "essential." While they are similar, "necessary" usually means it is required for a result, whereas "essential" often implies that the thing is absolutely fundamental or critical for survival.
