Pronunciation

  • Classical: [ˈtrãːf.fʊ.ɡa][1]
  • Ecclesiastical: [ˈtrans.fu.ɡa][1]

Forms

trānsfuga m (genitive trānsfugae); first declension[1]

Etymology

It is a noun of agent from Latin trānsfugiō (“to desert to the enemy”),[2][3] from trāns- and fugiō (“to flee”).[1] The verb fugiō goes back to Proto-Indo-European *bʰewg- (“to flee”).[4]

Earliest recorded meaning

Köbler's first source is Cicero,[3] who has “that deserter did not dare to tell the senate everything”.[2]

Semantic evolution

It is one who goes over to the other side, a deserter or renegade; a jurist in the Digest says that it means not only one who deserts to the enemy in war.[2][5] With a genitive it is one who deserts a place or a practice, as Lucan's “deserter of the world”, and in law a fugitive from custody, as from the mines.[2] Döderlein says that the perfuga goes over as a traitor to his side, while the ⟨transfuga⟩ is a waverer who changes sides; both are usually soldiers.[6]
