- homogeneous
- 1640s, from M.L. homogeneus, from Gk. homogenes "of the same kind," from homos "same" (see same) + genos "kind, gender, race, stock" (see genus). Earlier in this sense was homogeneal (c.1600). Homogenize "make similar" formed in Eng. 1886; its sense of "render milk uniform in consistency" is from 1904.
