Adjective
Alt. of Monadical
Source: Webster's dictionaryAn alternative nomenclature is derived in a similar fashion from the corresponding Greek roots; for example, niladic (or medadic), monadic, dyadic, triadic, polyadic, and so on. Source: Internet
Later, Peirce gave a mathematical reason for there being three categories in that although monadic, dyadic and triadic nodes are irreducible, every node of a higher valency is reducible to a "compound of triadic relations". Source: Internet
Concepts and expressions of this sort are monadic or "one-place" concepts and expressions. Source: Internet
The obvious convenience of functions of this kind, which appeared to be part of the language, led to the introduction of the monadic I-beam function for direct use by anyone. Source: Internet
