Pronunciation

  • IPA (Classical): [ˈmak.tʊs][1]
  • IPA (Ecclesiastical): [ˈmak.tus][1]

Forms

mactus (feminine macta, neuter mactum); first/second-declension adjective[1]

Etymology

Its origin is uncertain.[1] The OLD takes it as the participle of a verb *magere “to increase”, from the root of magnus “great”, as the TLL also reports.[2][3] De Vaan prefers Driessen's link with Proto-Celtic *make/o- “to raise, nourish”, from Proto-Indo-European *mh₂ḱ- (“to make long”), so “made long, made bigger”, the root of macer “thin”, since *mag-tos would have given *māctus.[4][1] Lewis and Short compared Ancient Greek μάκαρ (mákar, “blessed”).[5] Risch explains the formula macte estō as a blend, and mactō as “to pronounce that formula”.[4]

Earliest recorded meaning

De Vaan dates it from Cato, whose prayer says “be honoured by the offering of this pig”.[4][6] Köbler dates Cato 234–149 BC.[7]

Semantic evolution

In the language of religion it meant honoured, glorified, magnified, of the gods, almost only in the vocative macte, as in Cato's macte hōc porcō piāculō immolandō estō.[2][5][6] The phrase macte virtūte estō, “be honoured for your valour”, became a formula of praise, well done.[6][4] A second mactus, perhaps a back-formation from mactāre, meant struck or afflicted, in Lucretius.[2][7]
