 n syzygy In astronomy, the conjunction or opposition of a planet with the sun, or of any two of the heavenly bodies. On the phenomena and circumstances of the syzygies depends a great part of the lunar theory.
 n syzygy In ancient prosody, a group or combination of two feet. Ancient metricians varied in their use of this term. Some use it regularly for a dipody or (dipodic) measure. Others call a tautopody, or double foot, a dipody, but a combination of two different feet a syzygy. Some, accordingly, giving the name syzygy to tetrasyllabic feet (regarded by them as composed of two dissyllabic feet), speak of an iambic or a trochaic line as measured by dipodies, but an Ionic line as measured by syzygies—that is, by single Ionics considered as combinations of trochees and pyrrhics. A peculiar use is the restriction of the term syzygy to compound feet of five or six syllables.
 n syzygy In algebra, a linear function in the variables. See syzygetic.
 n syzygy In zoology, the conjunction of two organs or organisms by close adhesion and partial concrescence, without loss of their identity; also, the thing so formed, or the resulting conformation; a syzygium: a term variously applied. Zygosis or conjugation, as observed in various protozoans and other low organisms. See conjugation, 4, Diplozoön, and diporpa.
