Forms

familiarizar (first-person singular present familiarizo, first-person singular preterite familiarizei, past participle familiarizado)[1]

Etymology

It is formed from Portuguese familiar + -izar.[2][1][3][4] Vieira and Figueiredo in the 19th century already derive it from the adjective.[5][6]

The adjective familiar, recorded from the 13th century, is from Latin familiāris (“of the family, of the household”).[7]

Earliest recorded meaning

Houaiss dates the first record to the Monarquia Lusitana (1597–1693), in the participle familiarizado, and notes that this date is for an obsolete sense.[2] That sense is “to become related, to contract kinship”, which Houaiss marks as obsolete and Priberam as little used.[2][8]

Semantic evolution

Morais (1813) gives the sense “to make someone familiar in a house or in conversation”, “to accustom someone to something”, and the reflexive “to become familiar and intimate with someone”.[9] Vieira adds the use with com “to make used to work”.[5] Figueiredo (1899) has “to make common, popularize” and, for the reflexive, “to lose one's fear”.[6] A letter of 1822 in the Post Scriptum corpus has the infinitive.[10]

Timeline

  • 1597–1693 – familiarizado in the Monarquia Lusitana, in the obsolete sense “related by kinship”.[2]
  • 1813 – Morais defines “to make familiar” and “to accustom”.[9]
  • 1822 – familiarizar in a private letter.[10]
  • 1871–1874 – Vieira derives the verb from familiar.[5]
  • 1899 – Figueiredo adds “to popularize” and “to lose one's fear”.[6]
