The mathematician explained the inductive definition of the sequence before proving its properties.

The professor asked us to compare several conceptual definitions before the seminar.

Before starting the experiment, the team agreed on clear operational definitions so that every measurement would be comparable.

In semantics, an intensional definition states the meaning of a term by specifying the properties that all and only the entities it applies to possess.

To explain the sequence clearly, the professor introduced a recursive definition that starts with a base case and specifies how each subsequent term is formed.

In logic class, the professor contrasted an extensional definition with an intensional one to illustrate the difference between listing members and describing properties.

To clarify the concept for novices, the teacher relied on an ostensive definition, pointing to several examples and counterexamples.

To avoid ambiguity, the committee adopted an enumerative definition that explicitly listed every object covered by the term.

The philosopher explained the concept of definition by pointing during the lecture.

Children often learn words through definitions by pointing during everyday interactions with caregivers.
