Forms

rumor m (plural rumores)[1] A private letter of 1720 writes remor.[2]

Etymology

It is inherited from Latin rūmor (“noise; common talk, rumour”).[3][4][5][1] Houaiss dates the word to the 14th century, citing Cunha's index of medieval Portuguese.[3]

The same Latin word is Spanish rumor, Galician rumor, Catalan remor, French rumeur and Italian rumore; the Romance etymological dictionary lists it in every Romance language except Romanian.[6][7]

De Vaan traces the Latin word to Proto-Italic *roumōs and, with a question mark, to a word for “roaring”, of the root of Sanskrit and Old Church Slavonic verbs for roaring and of Ancient Greek ὠρύομαι (ōrúomai, “to howl”).[8] Wiktionary gives the root as Proto-Indo-European *h₃rewH- (“to shout, roar”).[1] The DHLF calls the Latin noun the only clear representative of that root in Latin.[9]

Earliest recorded meaning

The first records, of the 14th century, have the sense “fame, public report”; the sense “murmur, hubbub” follows in the 15th century.[3] The Horto do Esposo, in a manuscript of 1390–1437, uses the word.[10]

Semantic evolution

In Latin the word meant both the noise of many voices and the talk that goes round, and both senses passed to Portuguese.[11][12][3] Cunha gives “the noise of things moving” as the main sense.[4] Morais (1789) defines it as a din, a noise, and the fame that goes round, with an example from Camões's Lusíadas; his 1813 edition adds rumor do povo, the muffled voices of a crowd.[13][14] Folqman (1755) already has the murmuring of a complaining or rioting people.[15]

Modern dictionaries put the sense “unconfirmed report, piece of gossip” last and mark it as figurative, beside its synonym boato.[16][17] In Portugal rumor de lua is a change of the moon's phase, believed to affect health, and in law rumor público is a vague public report that leads to suspicion of a crime.[18][19]

Timeline

  • 1569 – Cardoso's dictionary has the word, with Latin rumusculus.[20]
  • 1720 – the spelling remor in a private letter.[2]
  • 1789 – Morais defines it as din, noise and fame.[13]
  • 1858 – first record of rumorejar.[4]

Usage notes

The vowel of the stressed syllable is closed, /ô/, in the singular and the plural rumores;[17] Aurélio distinguishes rumores from the verb form of rumorar, with an open vowel.[17] In Portugal leva rumor! is an exclamation that calls for silence or tells someone to go away.[22][18]
