Pronunciation

  • Classical: [kɔmˈpɛn.doː][1]
  • Ecclesiastical: [komˈpɛn.do][1]

Forms

compendō (present infinitive compendere); third conjugation, no perfect or supine stems[1]

Etymology

It is from Latin com- + pendō (“to weigh”), “to weigh together”.[2][3][1] De Vaan lists it among the compounds of pendō, which goes back to Proto-Italic *pend-e/o- (“to hang”) and Proto-Indo-European *(s)pend-e/-o- (“to spin”).[4]

Earliest recorded meaning

Its only classical example is in Varro, who explains compendium, a saving, as that which becomes one when it is weighed together: compendium, quod cum compenditur, ūna fit.[2][3][4][5]

Semantic evolution

Varro's explanation ties the verb to compendium, which de Vaan lists beside it among the derivatives of the same verb.[2][4] The verb itself is very rare.[2][3] A medieval poem on the reckoning of time uses it of small weights that together make up a larger unit.[6] In Poland it was used in the sense “to weigh in the mind, decide”.[7] English compendium, “a short summary”, comes from the noun, literally “that which is weighed together”.[8]

Timeline

  • 116–27 BC – Varro uses it to explain the noun compendium.[2][4][5]
  • 1580s – English borrows compendium, the noun Varro connected with it.[8]
