Forms

peor (the same form for both genders; plural peores)[1][2] Old Spanish also wrote peior, as in the Liber Regum and Berceo, and peyor in Aragonese texts;[3][4][5] Juan Ruiz has pior.[3][4][5] Pior is Aragonese and popular Castilian today, and Ribagorzan has pio.[6]

Etymology

It is inherited from Latin peior (“worse”), the comparative of malus (“bad”).[3][7][8][9] Old Spanish peior and, in old Aragonese texts, peyor keep the Latin /j/ between the vowels.[3][4]

The same Latin word is Italian peggiore, French pire, Old Occitan pejer, Old Catalan pejor and Old Galician-Portuguese peor.[10][6] The REW notes that the correct Latin form had a short vowel and a double /j/.[10]

The OLD and Gómez de Silva derive the Latin word from Proto-Indo-European *ped-yos-, a comparative of a root “to stumble, fall”.[11][9] Vox and Gómez de Silva connect that root with the word for “foot”, the worse being “the one who stumbles”.[11][9][12] Bénaben also takes it from a root “to fall”, with some hesitation.[13]

Earliest recorded meaning

The first record is the Cantar de mio Cid (c. 1140, in a 14th-century copy): qui buena dueña escarnece e la dexa después atal le contesca o siquier peor “whoever mocks a good lady and leaves her, may the same befall him, or worse”.[5][3][7] Menéndez Pidal classes this peor as an adverb of manner.[14]

Semantic evolution

The word has been in general use at all periods, as both adjective and adverb: Alfonso X's Lapidario calls some vipers peores than others, and the General Estoria says Joseph's brothers wished him peor after his dream.[3][2] Nebrija calls it the comparative of malo, and Covarrubias records ir de mal en peor “to go from bad to worse”.[15][16]

The Academy's dictionaries record the expressions peor que peor (1817), peor es lo roto que lo descosido (1843) and tanto peor (1884).[17][18][19] Baralt in 1855 and Román in Chile condemned de peor en peor as a copy of French de pis en pis, for the native de mal en peor.[20][21] With nouns of blame it works as “greatest”, as in su peor enemigo “his worst enemy”.[22] In Guatemala, Nicaragua and Paraguay the adverb also means “even more”.[23]
