Logic / Unit 2   Logic 047 short lesson, about 20 seconds

Definiendum and Definiens

Captions available

The idea

The definiendum is the term being defined; the definiens is the wording that does the defining.

In practice

"'Bachelor' means unmarried adult male." Definiendum: bachelor. Definiens: the rest.

Where people slip

The definiens is words about words — that's why definitions can be evaluated at all.
