The hollow or separation between a woman's breasts, especially as revealed by a low neckline
Low-cut Restoration costumes worn by the Misses Lockwood and Roc (see cut) display too much cleavage (Johnston Office trade term for the shadowed depression dividing an actress' bosom into two distinct sections).
The tendency of a mineral to split or separate along preferred planes when broken
The hollow or separation between a womans breasts, especially as revealed by a low neckline
Division into laminæ, like slate, with the lamination not necessarily parallel to the plane of deposition; usually produced by pressure
A woman's cleavage is the space between her breasts, especially the top part which you see if she is wearing a dress with a low neck. Tendency of a crystalline substance to split into fragments bounded by plane surfaces. Cleavage surfaces are seldom as flat as crystal faces, but the angles between them are highly characteristic and valuable in identifying a crystalline material. Cleavage occurs on planes where the atomic bonding forces are weakest; for example, galena cleaves parallel to all faces of a cube. Cleavage is described by its direction (as cubic, prismatic, basal) and by the ease with which it is produced. A perfect cleavage produces smooth, lustrous surfaces. Other degrees include distinct, imperfect, and difficult. See also fracture
the line formed by a groove between two parts (especially the separation between a woman's breasts) (embryology) the repeated division of a fertilised ovum the breaking of a chemical bond in a molecule resulting in smaller molecules the state of being split or cleft
n the tendency of a rock or mineral to break along planes determined by the crystal structure
The quality possessed by many crystallized substances of splitting readily in one or more definite directions, in which the cohesive attraction is a minimum, affording more or less smooth surfaces; the direction of the dividing plane; a fragment obtained by cleaving, as of a diamond
