(hydrate)
water absorption
Etymology
'hydrate' originates from French, specifically the word 'hydrater', where Greek 'hydor' meant 'water' and the suffix '-ate' (via Latin/Greek formation) indicated a related chemical/verb form.
'hydrate' changed from French word 'hydrater' (itself formed from Greek elements) and entered English in the 18th century as the scientific term 'hydrate' for compounds containing water and the verb meaning 'to combine with water.'
Initially, it meant 'to combine with or incorporate water' (chemical sense); over time it has broadened to include 'to supply or replenish water' (physiological/personal care sense) and the noun meaning 'a compound containing water.'
