Pronunciation

  • Brazil: /ˈmez.mu/, /ˈmẽ.mu/[1]
  • Rio-de-Janeiro: /ˈmeʒ.mu/, /ˈmeʁ.mu/[1]
  • Portugal: /ˈmeʒ.mu/, /ˈme.mu/[1]

Forms

mesmo (feminine mesma, masculine plural mesmos, feminine plural mesmas)[1] Old Galician-Portuguese wrote meesmo, mẽesmo, menesmo, medesmo, minismo, mijsmo and mismo.[2][3][4] Wiktionary lists the popular forms memo and mermo.[1]

Etymology

It is inherited from Vulgar Latin *metipsimus, written Old Galician-Portuguese meesmo in the oldest texts.[2][5][1] The Vulgar Latin word is a superlative of metipse, which joins the emphatic particle -met to ipse (“himself, the very”).[2][6][7] The particle strengthened the personal pronouns (egomet (“I myself”)), and Late Latin added the superlative ending to the combined form.[8][9]

The same Vulgar Latin word is Spanish mismo, French même and Italian medesimo.[1][10][11] Corominas, followed by the editors of the Crónica Geral, posits a colloquial variant *medipsimus, and rejects the REW's view that the Ibero-Romance word is a Gallicism.[3][9] Leite de Vasconcelos also preferred the form with /d/, since a /d/ from Latin /t/ would have been kept in Portuguese; the old form medesmo shows the /d/, and the usual old form shows its loss before the contraction to mesmo.[10][1]

Earliest recorded meaning

Lorenzo's first record is a charter of 1257, desse méésmo logar “of that same place”; an example of 1204 cited by Machado is false.[3] The word meant “same, not another” and, after a pronoun, “-self”: the Crónica Troiana writes elles meesmos alçauan as uelas “they themselves raised the sails”.[3]

Semantic evolution

In the 15th century Galician notaries used esso mesmo “likewise, also”.[12] Bluteau (1712) calls mesmo a pronoun that singles a thing out from all others, the Latin idem;[13][14] Morais (1789) gives “identical”, “in person” (eu mesmo) and sempre o mesmo “always the same, constant”.[13][14]

The adverbial uses, “even”, “really” and “exactly”, are recorded by Silva Bastos (1912), and today mesmo also stresses a time or place (hoje mesmo, aqui mesmo).[15][2][1] With que it forms the concessive conjunction mesmo que “even if”.[2] Cunha dates the derivative mesmice “sameness” to 1899.[5]

Timeline

  • 1257 – desse méésmo logar in a charter.[3]
  • 1265 – Houaiss's first date, for the feminine meesma.[2]
  • 1268–1293 – charters write minismo, mijsmo and medesmo.[3]
  • c. 1431 – mesmo in the Vida do honrado Infante Josafat (witness 1431–1446).[16]
  • 1712 – Bluteau gives mesmo as the Latin idem.[13]
  • 1789 – Morais records sempre o mesmo “constant”.[14]
  • 1899 – first record of mesmice.[5]
