The word "perfidy" derives from the Latin term "perfidia", which can be further broken down into "per" meaning "through, thoroughly" and "fides" meaning "faith, trust". In Latin, "perfidia" described a breach or betrayal of trust or faith. Over time, the term was adopted and evolved into "perfidie" in Old French, and finally entered the English language in the 16th century as "perfidy" with the same meaning.
