fenestra

Etymology and origin of the Latin word fenestra

History

Pronunciation

  • IPA (Classical): [fɛˈnɛs.tra][1]
  • IPA (Ecclesiastical): [feˈnɛs.tra][1]

Forms

fenestra f (genitive fenestrae); first declension[1] A contracted form festra is quoted from Ennius,[2][3] and Paulus' epitome of Festus says that the ancients said festra for fenestra.[4] Editors read fenstra in some lines of Plautus for the metre.[2]

Etymology

The origin is unknown.[2][5] The TLL notes a likeness to the Etruscan family name Fnesci and the Latin place name Fenestella,[4] and Wiktionary takes it to be a borrowing from Etruscan, though nothing is known of the meaning of the Etruscan base.[1] Köbler also mentions a possible Etruscan source.[5]

Older scholars linked it with Ancient Greek φαίνω (phaínō, “to show, shine”);[3][6] Walde derived it from the same root through a noun meaning “light”, and thought a borrowing from an unattested Greek word possible but no likelier.[7] Saalfeld lists it as a loan from φανήστρα (phanḗstra).[8] Ancient writers too sought a Greek source: Nonius derived it from the Greek for “to show”, and Isidore of Seville from the Greek word for light, saying that a window brings light into the house.[4]

Earliest recorded meaning

It is found from Plautus on,[5] meaning a window: in the Casina someone is to be shut up fast in a window recess.[2][3]

Semantic evolution

The Roman window was at first closed with wooden shutters, curtains or lattices, and only under the Empire with sheets of mica;[3][6] fenestra could also mean the shutter itself.[2] The word was soon used of other openings: a loophole for missiles in a wall or tower, a hole or breach,[2][3] the holes pierced in the ears for earrings,[3][6] and, in Cicero, the senses as the windows of the mind.[3][6] Figuratively it meant an opening or opportunity, as in Terence's “what a window you have opened to wickedness!”[2][3]

Medieval Latin used it for a shop window or shop,[9] for the revolving hatch through which things were passed into a convent, and for a cupboard in a church where the Eucharist was kept.[10]
