 (klē′vĭj)
n.
1. The act of splitting or cleaving.
2. The state of being split or cleft; a fissure or division.
3. Mineralogy The splitting or tendency to split of a crystallized substance along definite crystalline planes, yielding smooth surfaces.
4. Embryology
a. The series of mitotic cell divisions that produces a blastula from a fertilized ovum. It is the basis of the multicellularity of complex organisms. Also called segmentation.
b. Any single cell division in such a series.
5. Chemistry The splitting of a complex molecule, such as a polysaccharide, into simpler molecules.
6. Informal The cleft between a woman's breasts as revealed by a low-cut garment.

1. informal the separation between a woman's breasts, esp as revealed by a low-cut dress
2. a division or split
3. (Minerals) (of crystals) the act of splitting or the tendency to split along definite planes so as to yield smooth surfaces
4. (Biology) embryol Also called: segmentation (in animals) the repeated division of a fertilized ovum into a solid ball of cells (a morula), which later becomes hollow (a blastula)
5. (Chemistry) the breaking of a chemical bond in a molecule to give smaller molecules or radicals

cleav·age

(klē′vĭj)
1. Geology The breaking of certain minerals along specific planes, making smooth surfaces. These surfaces are parallel to the faces of the molecular crystals that make up the minerals. A mineral that exhibits cleavage breaks into smooth pieces with the same pattern of parallel surfaces regardless of how many times it is broken. Some minerals, like quartz, do not have a cleavage and break into uneven pieces with rough surfaces.
2. Biology In an embryo, the series of cell divisions by which a single fertilized egg cell becomes a many-celled blastula.
