γαλακτικός

Forms

γᾰλακτῐκός (galaktikós) m (feminine γᾰλακτῐκή, neuter γᾰλακτῐκόν); first/second declension^[1]

Etymology

It is formed from Ancient Greek γάλα (gála) + -ικός (-ikós), from the stem γαλακτ- (galakt-) of the noun for “milk”.^[1][2][3]

Earliest recorded meaning

Pape cites it from Dioscorides with the meaning “milk-white”.^[4] The earliest text in the GLAUx corpus is Hippolytus' Refutation of All Heresies, of a milk-white stone.^[5][6]

Semantic evolution

The ancient word only meant “milk-white”: Hippolytus uses it of a stone, and the Latin medical writer Marcellus Empiricus of an ointment.^[6][7][8] It is very rare, with a single instance in GLAUx.^[5]

Modern Greek γαλακτικός (galaktikós) is a learned formation from the same stem, meaning “of milk”; the Χρηστικό Λεξικό derives its chemical sense from French lactique.^[3][9] It is used in “lactic fermentation” and “lactic acid”.^[10] English galactic, by contrast, comes from Late Latin galacticus, from the Greek name of the Milky Way.^[11]
