Pronunciation

  • /ˈmi/, [ˈmi][1]

Etymology

It is inherited from Latin mihi (“to me, for me”), the dative of ego (“I”), in its everyday shortened form mī.[2][3][4][1][5] Its unstressed partner me comes from the Latin accusative mē; both forms are found from the earliest Old Spanish poetry on.[2][3]

Earliest recorded meaning

In the Cantar de mio Cid (c. 1140, known from a 14th-century copy) the hero greets a loyal vassal: Aún vea el día que de mí ayades algo “may I yet see the day when you have some reward from me”.[6][3] The word is already the stressed form used after a preposition.[6]

Semantic evolution

Old Spanish used mí after prepositions as the modern language does: Alfonso X's General estoria has entre mi & ti “between me and you”.[7] Salvá described it in 1846 as the form taken after any preposition except con, which gives conmigo.[8][4] Fixed phrases include ¡a mí!, a call for help, and a mí qué, “what do I care”.[9][10] In Costa Rica ¡porta mí! expresses indifference.[11]

Timeline

  • c. 1140 – the Cantar de mio Cid has de mí.[6][3]
  • 1272–1275 – Alfonso X's General estoria has entre mi & ti.[7]
  • 1846 – Salvá describes it as the form after any preposition except con.[8]
  • mid-20th century – rural Puerto Rican speech still uses mí where the standard has yo, as in entre tú y mí.[12]

Meanings

Pronoun

  1. me: the stressed form of the first-person singular pronoun, used after a preposition: Esa carta es para mí.[4][9][1]

Usage notes

After con the form is conmigo, not con mí.[10][4] Mí is always stressed; the unstressed object form is me.[9][2] Rural speech in Puerto Rico kept an older use of mí and ti after entre and in pairs joined by y (entre tú y mí) into the mid-20th century.[12]
