Lat. A conjugata argument, Lat. conjugatus, “related, of the same family”

Three types of argument are based on the fact that two words are materially related, depending on the nature of their relationship:

An etymological link S. True Meaning of the world.
A morphological link, S. Derived Words.
A phonic or graphic resemblance, S. Ambiguity.

Synonymy and antonymy are semantic relations.
