Forms

mismo (feminine misma, masculine plural mismos, feminine plural mismas, superlative mismísimo)[1] Old Spanish more often had meísmo (first in 1154) and meesmo or mesmo;[2][3] mismo itself is in the Cid.[2][3] Berceo has misme;[4][5] mesmo lived on in Old Aragonese, in Murcia and in popular speech, and Asturian has mesmu.[4][5]

Etymology

It is inherited from Old Spanish mesmo, inherited from Vulgar Latin *metipsimus.[2][6][1] The Vulgar Latin form, also given as *medipsimus, joins the emphatic particle -met, which Latin added to personal pronouns (egomet (“I myself”), tumet (“you yourself”)), and the emphatic superlative ipsimus of ipse (“himself, the very one”); in speech the particle had a variant -med.[2][7] Bénaben describes the steps: the emphasis of the doubled pronoun “I myself in person” wore off, the superlative was added, the pronoun was dropped, and the resulting long form was shortened by haplology.[8] The French tradition puts the joining of the two elements into metipse in the 5th century.[9]

The same Latin form is Portuguese mesmo, Galician mesmo, Asturian mesmu, French même (earlier Old French medisme and medesme, about 1050) and Italian medesimo.[10][1][9] The Latin pronoun alone gave the demonstrative ese.[11][7]

De Vaan explains the Latin pronoun as is with an element ⟨-pse⟩, probably from a particle ⟨-pe⟩ and the Proto-Indo-European pronoun *só.[12] Latin also had the superlative ipsissimus (“the very same”) from Plautus on.[12]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140) has mismo as a pronoun of identity, and a document of 1154 has the more usual old form meísmo.[2][3] The prose of Alfonso X already shows all three main uses: faz esso mismo “it does the same”, por esta misma razon “for this same reason”, and por si misma “by itself”, in the emphatic use after a pronoun.[13]

Semantic evolution

Mesmo and mismo long lived side by side: Nebrija in 1495 still wrote esso mesmo and alli mesmo, and a Mexican document of 1527 has yo mesmo and yo mismo in one passage.[14][15] Moliner lists mesmo and meísmo as old forms.[16]

From Autoridades on, the Academy defined the same three senses: identity (“not another”), likeness (“the same colour”) and emphasis after a personal pronoun (yo mismo).[17][18] Autoridades derived the word from Italian medesimo, and the Academy's dictionaries of 1884 and 1899 from a Latin enclitic metipsum.[17][19][20] In 1869 the Academy added the use after adverbs (hoy mismo, aquí mismo), noting that it then never takes a feminine ending.[21]

In Colombia mismo after a noun means “complete, utter”, as in un burro mismo “a perfect fool”.[22] In several American countries ahí mismo means “at that very moment”.[23] Philippine Spanish passed the word into Tagalog and Chavacano as mismo.[1]
