(underhydrate)
insufficient water
Etymology
'underhydrated' is formed in modern English from the prefix 'under-' + the verb 'hydrate', where 'under-' conveys 'insufficient' or 'too little' in compounds and 'hydrate' ultimately derives from Greek 'hydor' meaning 'water'.
'hydrate' entered English via New Latin/French formations (e.g. New Latin 'hydratus', French 'hydrater') from Greek 'hydor' ('water'), and compounds with 'under-' were formed in English by compounding that prefix with verbs like 'hydrate' to express insufficiency ('under-' + 'hydrate' → 'underhydrate' → 'underhydrated').
Originally, 'hydrate' meant 'to combine with or supply water'; over time the compound 'underhydrate/underhydrated' came to mean 'supplied with too little water' or 'insufficiently hydrated'.
