Synonym Chooser
Some common synonyms of essential are cardinal, fundamental, and vital. While all these words mean "so important as to be indispensable," essential implies belonging to the very nature of a thing and therefore being incapable of removal without destroying the thing itself or its character.
conflict is essential in drama
While in some cases nearly identical to essential, cardinal suggests something on which an outcome turns or depends.
a cardinal rule in buying a home
While the synonyms fundamental and essential are close in meaning, fundamental applies to something that is a foundation without which an entire system or complex whole would collapse.
fundamental principles of algebra
The words vital and essential are synonyms, but do differ in nuance. Specifically, vital suggests something that is necessary to a thing's continued existence or operation.
