Pronunciation

Forms

quase (not comparable)[1] The 15th-century texts write quassy, quasi, cassy, cazy, caise, caisi, caje, quaije, acaije, acaise and aquaijo beside quase.[2][3] Wiktionary lists the variants quási, quasi, quazi, quaze and quaje.[1]

Etymology

It is inherited from Latin quasi (“as if; just as; almost”).[2][3][4][1] Wiktionary calls it a semi-learned borrowing, and Nascentes notes archaic and popular forms without the /w/ of the learned spelling, citing Nunes's historical grammar.[1][5]

The same Latin word is Spanish casi and Spanish cuasi, French quasi, Italian quasi and Old Occitan cais.[6][1] Corominas explains the Spanish pair by a stressed and an unstressed pronunciation of the word.[7]

The Latin word is a univerbation of quam (“how, as”) and sī (“if”), with both vowels shortened; old inscriptions write it quasei.[8][1]

Earliest recorded meaning

Lorenzo's chronology has quassy nada “almost nothing” in a text of 1460, the date Houaiss gives for the first record.[9][2] A witness of the Livro das tres vertudes a inssinança das damas made after 1450 writes casy.[10] The sense is the modern one, “almost, nearly”.[9]

Semantic evolution

Nascentes quotes Azurara's Crónica de Guiné for the popular form: Que casy todos o avyam por maravilha “so that nearly all held it a marvel”.[5] The forms caje, quaje and quaji appear in the glossary of Sá de Miranda.[9] The Latin sense “as if” survived for a time in a conjunction, which the DLP marks as no longer used.[11]

The popular forms without /w/ still live in the dialects: the REW cites quaise from Lisbon and caize and acajo from the Minho, and the TLPGP records acaije, aquase, caije, cais, quaije and quais in Portugal.[6][12] In Cape Verdean Portuguese the word has come to mean “perhaps”.[13][14]

Timeline

  • 1460 – quassy nada “almost nothing”, the first dated record.[9][2]
  • second half of the 15th century – casy in a witness of the Livro das tres vertudes made after 1450.[10]
  • 1542 – a private letter writes casy.[15]
  • 1741 – a letter from Santarém writes quazi.[16]

  2. almost, nearly, a little less than: Já passaram quase dez anos.[2][13][17]
  3. approximately, more or less; to some degree: O livro está quase pronto.[2][11]

Usage notes
