definiendum

Borrowed from Latin dēfīniendum, gerund of dēfīniō.

definiendum (plural definienda)

1. (semantics) The term—word or phrase—defined in a definition.
   • 1991, William Thomas Parry; Edward A. Hacker, Aristotelian Logic, SUNY Press, →ISBN, page 84:

     However, most advocates of the importance of real definition have limited the definiendum to certain kinds of things: usually an abstract entity or a concept.

   • 2013, Edward Craig, editor, Concise Routledge Encyclopedia of Philosophy, Routledge, →ISBN, page 198:

     The objects themselves are the definienda of the definition. The first set of properties through which the definienda are collected together to form a group is called ‘the limiting properties of being the definienda of the definition’.
