Ultimate origin

Pronunciation

Forms

retta f (only in the phrase dare retta)[2][3] Lucchese has dare aretta, and other Tuscan dialects arétta.[4][5]

Etymology

The word for attention is inherited from Latin arrēctam, the feminine of the past participle of Latin arrigō (“to raise, prick up”), with the loss of its first syllable.[4][6][7] Latin used arrigō with Latin auris (“ear”) for pricking up the ears, and the Italian phrase goes back to one meaning “with ear pricked”.[4][3][8] GRADIT and Treccani give this origin with a “perhaps”.[2][9] Latin arrigō is formed from Latin ad- and Latin regō (“to direct, guide”).[6][1][10]

Earliest recorded meaning

DELI's first record of dar retta “to listen, pay attention” is in L. Lippi, before 1665; the GDLI quotes it from his Malmantile.[4][11]

Semantic evolution

The notes to the Malmantile (1688) record that the old writers used dar retta in another sense, in war, for withstanding an attack, as Latin said impetum sustinere.[4] Giovanni Villani's fare retta in that sense is a separate noun, from reggere.[11][12]

In modern Italian the phrase means listening to someone, taking notice of what they say, believing them, or following their advice, and figuratively giving in to an impulse.[3][7][8] Dammi retta asks the listener to take advice, and a dar retta a lui means “if we believe him”.[3][8]

Timeline

  • Before 1665 – L. Lippi has dar retta.[4]
  • 1688 – The notes to the Malmantile discuss the older military sense.[4]

Meanings

Noun

  1. Only in the phrase dare retta: to listen or pay attention to someone or something: Gli parlavo da mezz'ora, ma non mi dava retta.[2][3][7]
  2. In dare retta: to believe someone or trust what is said: Non dare retta alle voci che girano in ufficio.[3][7][8]
  3. In dare retta: to follow someone's advice: dammi retta, take my advice.[3][7][13]

Pronunciation

Forms

retta f (plural rette)[1]

Etymology

The word for the fee is borrowed from Latin rēcta (“regular, agreed”), understood with Latin summa (“sum”): “the regular sum”.[4][6][3] Sabatini–Coletti, Gabrielli and Treccani see in it the feminine of retto used as a noun, from a phrase meaning “fair sum”, and Wiktionary also offers that origin as a possibility.[7][14][13][1] Tommaseo explained it from reggere, because the fee “sustains” life, and Treccani mentions this view as less likely.[4][13] DEI took it from the plural of Latin rēctum (“what is due by right”).[5]

Earliest recorded meaning

DELI's first record is in Fanfani's Tuscan vocabulary of 1863, for the fee paid by a boarder in a college;[4] Rezasco in 1881 called it a fine word then common in Tuscany and other provinces.[4]

Semantic evolution

The word belonged to Tuscan and central Italian use.[5][4] Tommaseo recorded mezza retta, the half fee granted to some pupils as a favour, and stare or tenere a retta, to board or to take in boarders.[11][14] Today the fee is paid in colleges, boarding schools, hostels, clinics and old people's homes, usually every month.[3][7][11]

Timeline

  • 1863 – Fanfani's Tuscan vocabulary records the word.[4][6]
  • 1881 – Rezasco notes its wide use in Tuscany and other provinces.[4]

Meanings

Noun

  1. A fixed fee, usually monthly, paid for board and lodging in a college, boarding school, home or similar institution: La retta del collegio è aumentata quest'anno.[3][7][14][13]

retta3 straight line

Confidence
Established
Formation
Derivation
First attested
1642 before 1642, G. Galilei
Ultimate origin
Latin regō

Pronunciation

Forms

retta f (plural rette)[1]

Etymology

The word for the straight line is from Italian retto (“straight”), its feminine used as a noun, an ellipsis of linea retta.[6][4][1] It renders Latin rēcta (“straight (line)”), the feminine of Latin rēctus used with līnea understood, already in classical Latin.[11][2][12] The adjective is a learned word from rēctus, the past participle of regō (“to direct, guide in a straight line”).[6][4]

Earliest recorded meaning

DELI dates the geometric noun to Galileo, before 1642.[4] Dante already has la retta lingua (1293–1294) and una linea retta (1304–1308) with the adjective.[4] Nocentini and GRADIT date the noun to 1872.[6][2]

Semantic evolution

The noun is a basic notion of geometry: the shortest line between two points, prolonged without end in both directions.[2][11] In Euclidean geometry it is defined only implicitly through the postulates.[2][11][12] By extension it is a line that represents a statistical or economic trend on a graph.[2] Many technical phrases name kinds of straight line, such as retta numerica (number line) and fascio di rette (pencil of lines).[2]

Timeline

  • 1293–1294 – Dante writes la retta lingua.[4]
  • 1304–1308 – Dante writes una linea retta.[4]
  • Before 1642 – Galileo uses retta as a noun in geometry.[4]
  • 1872 – The date Nocentini and GRADIT give for the noun.[6][2]

Meanings

Noun

  1. (geometry) A straight line: the shortest line joining two points, extended without end in both directions; a primitive notion of Euclidean geometry.[2][9][11]
  2. By extension, a straight line on a graph that represents a statistical or economic trend.[2]

Word family

  • semiretta

Usage notes

Retta is also the feminine of the adjective retto, as in linea retta, and a form of the past participle of reggere.[1][12] An old noun retta “resistance against an enemy”, in fare retta, is recorded in Giovanni Villani and other early writers.[11][12]
