A rare word meaning tending to break up or break faith; characterized by disloyalty or unfaithfulness.
From Latin 'fides' (faith) + 'fragus' (breaking). This is an extremely rare English word, appearing mostly in historical texts from the 1600s-1800s and now considered virtually obsolete.
This word is so obscure that most English dictionaries don't even include it—it's like finding an archaeological artifact of the English language, a word that almost nobody uses anymore.
