What Z word is the antonym of nadir?
Nadir Nadir The nadir (, ; from / ALA-LC: "naẓīr", meaning "counterpart") is the direction pointing directly "below" a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface there. Since the concept of "being below" is itself somewhat vague, scientists define the nadir in more rigorous terms. Specifically, in astronomy, geophysics and related sciences (e.g., meteorology), the nadir at a given point is the local vertical direction pointing in the direction of the force of gravity at that location. The direction opposite the nadir is the zenith. Nadir is
Auto-antonym Auto-antonym An auto-antonym or autantonym, also called a contronym or contranym, is a word with multiple meanings (senses) of which one is the reverse of another. For example, the word "cleave" can mean "to cut apart" or "to bind together". This phenomenon is called enantiosemy, enantionymy or antilogy ("enantio-" means "opposite"). An enantiosemic term is necessarily polysemic. The terms "autantonym" and "contronym" were coined by Joseph Twadell Shipley in 1960 and Jack Herring in 1962, respectively. An auto-antonym is alternatively called an antagonym, Janus word (after the Roman god with two faces), enantiodrome, self-antonym, antilogy, or addad (Arabic, singular didd).
