• None
  • Either of two points in the orbit of a solar system body where the body is in opposition to or in conjunction with the sun.
  • Either of two points in the orbit of the moon when the moon lies in a straight line with the sun and Earth.
  • The configuration of the sun, the moon, and Earth lying in a straight line.
  • The combining of two feet into a single metrical unit in classical prosody.
  • In <em>astronomy</em>, 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.
  • In <em>ancient prosody</em>, a group or combination of two feet.
  • In <em>algebra</em>, a linear function in the variables. See <internalXref urlencoded="syzygetic">syzygetic</internalXref>.
  • In <em>zoology</em>, 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.
  • The point of an orbit, as of the moon or a planet, at which it is in conjunction or opposition; -- commonly used in the plural.
  • The coupling together of different feet.
  • None
  • Any one of the segments of an arm of a crinoid composed of two joints so closely united that the line of union is obliterated on the outer, though visible on the inner, side.
  • The immovable union of two joints of a crinoidal arm.
  • The intimately united and apparently fused condition of certain low organisms during conjugation.
  • the straight line connecting the earth, the sun, and the moon or a planet, when the latter is in conjunction or opposition; -- used chiefly of the moon.
  • A kind of unity, namely an <xref>alignment</xref> of three <xref>celestial</xref> bodies (for example, the <xref>Sun</xref>, <xref>Earth</xref>, and <xref>Moon</xref>) such that one body is directly between the other two, such as occurs at an <xref>eclipse</xref>
  • An <xref>archetypal</xref> pairing of <xref>contrasexual</xref> opposites, symbolizing the <xref>communication</xref> of the <xref>conscious</xref> and <xref>unconscious</xref> minds
  • A <xref>relation</xref> between <xref>generators</xref> of a <xref>module</xref>
  • The <xref>fusion</xref> of some or all of the <xref>organs</xref>
  • The <xref>association</xref> of two <xref>protozoa</xref> end-to-end or <xref>laterally</xref> for the purpose of <xref>asexual</xref> exchange of <xref>genetic</xref> material
  • The pairing of <xref>chromosomes</xref> in <xref>meiosis</xref>
  • the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational system
