anhydrated
|an-hy-dra-ted|
/ænˈhaɪdreɪtɪd/
(anhydrate)
without water; make water-free
Etymology
'anhydrated' originates from Greek and French roots: the prefix 'an-' from Greek 'an-' meaning 'without', combined with 'hydrate' from French 'hydrate' (ultimately from Greek 'hydōr' meaning 'water'), plus the English participial suffix '-ed'.
'hydrate' entered English via French 'hydrate'; English then formed the verb 'anhydrate' by adding the Greek-derived privative prefix. The participial/adjectival form 'anhydrated' developed in Modern English scientific usage.
Initially, it meant 'to make something without water; to remove water from a substance', and it now also functions adjectivally as 'made anhydrous; with water removed'.
