Etymology
The word 'lactation' is a direct descendant from the Latin lactationem, the noun of action from lactare, meaning "to suckle" or "to give milk". The verb lactare itself is derived from lac (milk), a Latin word with deep Indo-European roots, traceable to the Proto-Indo-European root glakt-, also meaning milk. The logical construction of the modern term is beautifully transparent: it combines the ancient root for "milk" with a suffix denoting "the process of", thus literally meaning "the process of producing milk". This etymological path elegantly connects the biological function directly to its most essential substance.
