Forms

Etymology

It is formed from Latin angulus (“corner, angle”) + -ārius.[2][3]

Earliest recorded meaning

The earliest example the OLD records is in an inscription from Puteoli, a law on building a wall, where it is spelled angolaria and refers to pieces set at the corners.[2][4][3]

Semantic evolution

In Classical Latin it is rare: besides the Puteoli inscription, the Digest quotes the jurist Proculus on a lake called Angularius,[4][3] which the TLL takes as a proper name.[4] A Greek–Latin glossary renders it with a Greek word for “of a corner”.[3]

In the Latin of 16th-century Poland it was used of things done “in a corner”, that is secretly or underhand, and of a stone standing at the corner of a boundary.[5] Wiktionary traces Romanian ungher “corner” to it.[1]

Timeline

  • 533 AD – The Digest quotes Proculus on the lake called Angularius.[4][3][6]
  • 1520 – A Polish document uses it in the sense “clandestine”.[5]
