Brit.

/ˈkɒlɔɪd/, U.S.

/ˈkɑˌlɔɪd/

Etymology: < Greek κολλο- combining form of κόλλα glue + -ειδης -form: see -oid suffix.

A. adj. Of the nature or appearance of glue.

1. Pathology. colloid substance, colloid tissue, colloid matter, colloid corpuscles, colloid spheres: a homogeneous or slightly granular gelatinous substance into which the cells are changed in certain forms of degeneration of tissue ( colloid degeneration, colloid metamorphosis). colloid cancer: a form of cancer in which colloid degeneration takes place.

1876 J. Van Duyn & E. C. Seguin tr. E. L. Wagner Man. Gen. Pathol. 329 Colloid metamorphosis consists in the transformation of tissues into a completely homogeneous, colorless or faint yellow, dull, translucent, sometimes fluid or soft, glue-like..substance.

2. Chemistry. Applied by Graham, 1861, to describe a peculiar state of aggregation in which substances exist; opposed to crystalloid. Substances in the colloid state are characterized by little or no tendency to diffuse through animal membranes or vegetable parchment, do not readily crystallize, are inert in their chemical relations, but are highly changeable. So called because gelatin may be taken as the type of the class.

1867 H. Spencer First Princ. (ed. 2) ii. xiii. §101. 295 Matter has two solid states, distinguished as crystalloid and colloid; of which the first is due to union of the individual atoms or molecules, and the second to the union of groups of such individual atoms or molecules.
