Twin
Twin Twin, n. 1. One of two produced at a birth, especially by an animal that ordinarily brings forth but one at a birth; -- used chiefly in the plural, and applied to the young of beasts as well as to human young. [1913 Webster]

2. pl. (Astron.) A sign and constellation of the zodiac; Gemini. See {Gemini}. [1913 Webster]

3. A person or thing that closely resembles another. [1913 Webster]

4. (Crystallog.) A compound crystal composed of two or more crystals, or parts of crystals, in reversed position with reference to each other. [1913 Webster]

Note: The relative position of the parts of a twin may be explained by supposing one part to be revolved 180[deg] about a certain axis (called the twinning axis), this axis being normal to a plane (called the twinning plane) which is usually one of the fundamental planes of the crystal. This revolution brings the two parts into parallel position, or vice versa. A contact twin is one in which the parts are united by a plane surface, called the composition face, which is usually the same as the twinning plane. A penetration twin is one in which the parts interpenetrate each other, often very irregularly. Twins are also called, according to form, cruciform, geniculated, etc. [1913 Webster]
