hovoide is incorrectly written, and should be written as "ovoid" being its meaning:
hovoide = ovoid ovoideEl is a closed Planar curve composed of four arches of circumference: one of them is a semicircle and two others are equal and symmetrical. Its name derives from its similarity to the longitudinal section of an egg.It has two orthogonal axes, called major and minor. It has four centers of curvature. Unlike the oval, it only has an axis of symmetry.
