- Required by the nature of things or by circumstances; necessary; so needful that it cannot be dispensed with; indispensable.
- Synonyms Essential, etc. See necessary.
- n. That which is necessary; something essential or indispensable.
- n. Synonyms Requisite, Requirement. That which is required by the nature of the case, or is only indirectly thought of as reqnired by a person, is called a requisite; that which is viewed as required directly by a person or persons is called a requirement: thus, a certain study is in the one aspect a requisite and in the other a requirement for admission to college; we speak of the requisites to a great commander or to a successful life; of the requirements in a candidate for a clerkship. Hence, generally, a requisite is more absolutely necessary or essential than a requirement; a requisite is more often material than a requirement; a requisite may be a possession or something that may be viewed as a possession, but a requirement is a thing to be done or learned.
