Pronunciation

  • Classical: [pɔsˈtiː.kʊs][1]
  • Ecclesiastical: [posˈtiː.kus][1]

Forms

postīcus (feminine postīca, neuter postīcum); first/second-declension adjective[1] An inscription of Curubi has posteicuus, which the OLD takes as a spelling of postīquus.[2] The TLL confirms the long ⟨ī⟩ from the poets.[3]

Etymology

It is from Latin post (“behind, after”) + -īcus,[2][1][3] formed like antīcus from ante.[2][4] De Vaan explains it as Proto-Indo-European *posti-h₃kʷ-o- (“facing the back”), with the same second part as ⟨antīcus⟩.[5] The preposition goes back to Proto-Italic *posti (“behind, after”) and Proto-Indo-European *pos(ti) (“after”).[5] The grammarian Priscian already derived it from ⟨post⟩.[3]

Earliest recorded meaning

Plautus has it of a back door: est etiam hīc ōstium aliud postīcum nostrārum aedium, “there is also another door at the back of our house here”.[4][5][6]

Semantic evolution

It was used above all of buildings and their parts, situated at the back:[2] Varro speaks of back walls and the back part of a house,[4] and Livy of the rear of a house.[4] Persius has grimaces made behind someone's back, postīcae sannae,[4] and Solinus the hind feet of an animal.[4][7] As nouns, postīca and postīcum meant a back door;[7] postīcum also meant a back building, the rear of a temple, and the backside.[7] Land surveyors called the side of a plot facing away from them postīca, opposite antīca.[7][4]

In Medieval Latin, especially as a noun, it was a back door or postern;[8] an Anglo-Norman glossary renders it by ⟨posterne⟩.[8]
