What does abjurer mean?
An abjurer is a person who abjures — that is, one who formally, solemnly, and often publicly renounces a belief, allegiance, opinion, or course of conduct. The word derives from the verb abjure, which combines the Latin prefix ab- ('away from') with iurare ('to swear'), so at its root an abjurer literally swears something away. Historically, the term carried real legal weight: in medieval England, a person accused of a crime could become an abjuror by swearing the oath of abjuration, pledging to leave the realm permanently instead of facing trial. Today the word survives mainly in formal or literary contexts, describing converts who repudiate former ideologies, writers who recant earlier positions, or officials who disavow prior claims. Its connotations are weighty and deliberate — an abjurer does not merely change their mind but formally forswears what they once held.

Etymology of abjurer
Abjurer comes from the verb abjure, borrowed into English from Latin abiurare, formed from ab- ('away from') plus iurare ('to swear'). It entered English via Old French abjurer, appearing from around the late Middle Ages onward, particularly in religious and legal contexts such as the renunciation of heresy or the oath of abjuration. It shares its Latin root with words such as adjure, perjury, and jury, all ultimately deriving from ius/iurare, the Latin notion of oath and law.
