deteriorate: deteriorate: [16] The meaning of deteriorate resides etymologically in its first syllable, which represents the Latin preposition dē ‘down’. To this was added the adjectival suffix -ter, to produce *dēter ‘bad’, and this in turn was modified with the comparative suffix -ior to dēterior ‘worse’. Dēterior formed the basis of the verb dēteriorāre ‘get worse’, source of English deteriorate.
deteriorate (v.): 1640s (as a past participle adjective, 1570s), from Late Latin deterioratus, past participle of deteriorare "get worse, make worse," from Latin deterior "worse, lower, inferior, meaner," contrastive of *deter "bad, lower," from PIE *de-tero-, from demonstrative stem *de- (see de).
