Lactation

Lac*ta"tion\, n. A giving suck; the secretion and yielding of milk by the mammary gland.

lactation 
1668, "process of suckling an infant," from Fr. lactation, from L. lactationem (nom. lactatio) "a suckling," from L. lactatus, pp. of lactare "suckle," from lac (gen. lactis) "milk," from PIE base *glact- (cf. Gk. gala, gen. galaktos "milk"). Meaning "process of secreting milk from the breasts" first recorded 1857; lactate (v.) in this sense is a back-formation from 1889. Lactic acid is from 1790; so called because it was obtained from sour milk. M.Ir. lacht, Welsh llaeth "milk" are loan words from Latin.
