- adj. Shaped like a cone.
Century Dictionary and Cyclopedia
- Having the form of cone; conoidal.
- n. In geometry: A solid formed by the revolution of a conic section about its axis. A skew surface which may be generated by a straight line moving in such a manner as to touch a straight line and curve, and continue parallel to a given plane. A surface generated by the revolution of an arc of a circle about its sine. If the conic section is a parabola, the resulting solid is a parabolic conoid, or paraboloid; if a hyperbola, the solid is a hyperbolic conoid, or hyperboloid; if an ellipse, an elliptic conoid, a spheroid, or an ellipsoid. But the term conoid is often used to include the hyperboloids and paraboloids and to exclude the spheroids. This is the meaning of the Greek word with Archimedes.
- n. In anatomy, the conarium or pineal body.
- In conchology, resembling or having the characters of the Conidæ.

Examples
