Pronunciation

  • Classical: [koˈae̯.kʷoː][1]
  • Ecclesiastical: [koˈɛː.kʷo][1]

Forms

coaequō (present infinitive coaequāre, perfect active coaequāvī, supine coaequātum); first conjugation[1]

Etymology

It is from Latin con- + aequō (“to make level, make equal”).[2][1][3] De Vaan derives aequō from the adjective aequus (“level, equal”), probably from a form ⟨*aikwos⟩, for which he finds no convincing etymology.[4]

Earliest recorded meaning

The TLL dates it from Cato,[5] who uses it in the De agricultura of levelling a threshing floor.[6][7][8]

Semantic evolution

In its literal sense it is used of levelling ground: Sallust has montēs coaequāre, to level mountains, Columella of levelling clods and furrows, and an inscription of levelling a small shrine.[2][6][9] Figuratively it means to put on the same level or treat as equal: Cicero uses it of treating everything alike, and the second letter to Caesar attributed to Sallust of making everyone's favour equal.[2][9] A public law uses it of adjusting measures by the official weights.[2] In Augustine it means to compare, and Stelten gives the Church Latin senses “make equal, fill up, rank with”.[9][10] Medieval writers used it of levelling a forest and of demolishing, of smoothing, and of dividing equally, and also in mathematics and music.[11]
