defectio

From dēficiō +‎ -tiō.

• (Classical) IPA^(key): /deːˈfek.ti.oː/, [deːˈfɛk.ti.oː]

dēfectiō f (genitive dēfectiōnis); third declension

1. defection, desertion
2. rebellion, revolt (of a city)
   • 27 BCE – 25 BCE, Titus Livius, Ab urbe condita libri 26.1:

     Ea tum cura maxime intentos habebat Romanos, non ab ira tantum, quae in nullam unquam ciuitatem iustior fuit, quam quod urbs tam nobilis ac potens, sicut defectione sua traxerat aliquot populos, ita recepta inclinatura rursus animos uidebatur ad ueteris imperii respectum.

     This concern in particular troubled the mindful Romans at the time, not so much because of anger, which has never been more justified against any other city, rather because a city so noble and powerful, in the same way that it had attracted the support of a number of communities by its revolt, was thought would again turn attention back towards respect for the previous government once recaptured.

3. failing, failure, deficiency, want, disappearance
4. eclipse
5. ellipsis
6. a fainting spell, failure of energy or stamina
