Forms

musgo m (plural musgos)[1]

Etymology

It is inherited from Latin muscus (“moss”), written Old Galician-Portuguese musgo in the oldest texts.[2][1][3][4] To explain the /g/, Nascentes proposes an epenthetic form *musico, compare the popular musga for música, while Cornu, as Nascentes reports, assumed an earlier *musco voiced as in visco beside visgo.[3][5] For the Spanish word Corominas suspects a semi-learned character.[6]

The same Latin word is Galician musgo, Spanish musgo and Italian musco.[7][5][1]

The Latin word is cognate with mos, moss and musaĩ.[8] Wiktionary takes it to Proto-Indo-European *mews-, the source also of *musą and *mъxъ.[1]

Earliest recorded meaning

Houaiss dates the word to 1265, from the documents of Portel.[2] Barbosa's dictionary of 1611 describes it as what grows on trees, stones and fountains, and gives the Latin emuscare arbores for clearing trees of moss.[9]

Semantic evolution

Bluteau (1712) still described moss as a little herb that grows on tree trunks and branches and among stones, and Morais (1789) as a parasitic herb whose structure cannot be fully seen.[10][11] Vieira (1871–1874) defines it as the cryptogams with stem and leaves, and Houaiss now uses it for the bryophytes and, in the plural, for their class.[12][2] Many plant names are compounds with it, such as musgo-da-islândia.[13] In some regions of Portugal it also means dry pine needles, and figuratively the deep wrinkles of an old face.[14][15]

Timeline

  • 1265 – Houaiss's first date.[2]
  • 1611 – Barbosa: moss of trees, stones and springs.[9]
  • 1712 – Bluteau quotes a line on musgos de esmeralda “emerald mosses”.[10]
  • 1789 – Morais defines it as a parasitic herb.[11]
  • 1871–1874 – Vieira gives the botanical definition.[12]

Meanings

Noun

  1. (botany) moss: any of the small bryophytes with stem and leaves that grow on damp rocks, tree trunks and walls.[2][4][1]
  2. A cover of such plants over a surface.[14]
  3. (in the plural, botany) musgos: the class of bryophytes made up of these plants.[2][15]
  4. (Portugal, regional) Dry pine needles, caruma.[14][15]

Usage notes

Old Portuguese had a separate noun musgo “musk”, which Cunha derives from Arabic misk and dates to the 14th century, with a variant musco in the 15th; the Crónica Geral of 1344 says of a man that neither he nor his clothes cheirauã a musgo “smelled of musk”.[16][17] The modern word for musk is almíscar.[16]

The dictionaries also record an adjective musgo for sheep and other animals with very small ears, of doubtful origin according to the old Caldas Aulete, and an obsolete musgo “muscle”.[18][14][19]
