Pronunciation

  • Brazil: /kaˈlo.zu/[1]
  • Portugal: /kɐˈlo.zu/[1]

Forms

caloso (feminine calosa, masculine plural calosos, feminine plural calosas, comparable, metaphonic)[1] The first record, of 1570, is spelt calloso, and Bluteau still gives caloso, ou calloso.[2][3][4]

Etymology

It is borrowed from Latin callōsus (“hard-skinned, tough”), first recorded in 1570.[2][3] The Latin adjective is formed from callum (“hardened skin”) with the suffix -ōsus.[5][1] Wiktionary analyses the Portuguese word as calo with the suffix -oso.[1]

The same Latin word was taken into Galician caloso, Spanish calloso, Italian calloso and French calleux.[6][1]

Earliest recorded meaning

Houaiss records the word in 1570, in the spelling calloso, with the basic sense “having calluses”.[2]

Semantic evolution

Bluteau's dictionary glosses the word “that has calluses” and adds the anatomical corpo caloso, a white, hard body under the division of the brain that joins its two halves, which the anatomists call corpus callosum.[4] Morais (1789) keeps both senses, “made into a callus” and the part of the brain.[7] Modern dictionaries extend the word to anything rough or hard like a callus and, figuratively, to what has grown hard or insensitive over time; the DLP also gives the sense “chronic, inveterate”.[2][8][9]

Timeline

  • 1570 – first record, spelt calloso.[2][3]
  • 1712–1728 – Bluteau gives caloso, ou calloso and the anatomical corpo caloso.[4]
  • 1789 – Morais defines it as “made into a callus” and records corpo caloso.[7]
  • 1871 – Vieira enters caloso only as a cross-reference to calloso.[10]

Meanings

Adjective

  1. Having calluses, especially many of them; callused (calejado): Tinha as mãos calosas do trabalho no campo.[2][11][12][1]
  2. Hard or rough in texture, like a callus.[2][13]
  3. (figurative) Grown hard, resistant or insensitive with time.[2][9]
  4. Chronic, inveterate.[8]
  5. Having or forming a rounded, harder prominence; hence (anatomy) corpo caloso, the corpus callosum that joins the two hemispheres of the brain.[2][12][9]

Noun

  1. (anatomy) The corpus callosum, short for corpo caloso.[13]

Usage notes

The stressed vowel is closed /o/ in the masculine singular and open /ɔ/ in the feminine and the plural (calosa, calosos).[12][9]

The TLPGP records from a survey in Portugal the regional senses “dirty”, “old” and “broken into pieces”.[14]
