Abjure vs. Adjure – Which is Correct?

The words abjure and adjure are often confused due to their similar sound and spelling, but they carry distinct meanings. To abjure means to formally renounce or reject something, often under oath. To adjure means to earnestly request or command someone to do something, typically with great solemnity or an appeal to a higher power.

Abjure or Adjure – Which is Correct?

Both abjure and adjure are correct and valid verbs in American English, but they have opposite implications. The core difference lies in their prefixes, which significantly alter their meanings. Abjure stems from Latin roots meaning “to swear away from,” indicating a formal rejection or withdrawal. In contrast, adjure comes from roots meaning “to swear to,” signifying a solemn appeal or command directed towards someone.

The Best Trick to Remember the Difference

A powerful mnemonic to distinguish between these two words involves their prefixes:

• Remember abjure by thinking of “absent” or “abstain.” The prefix “ab-” means “away from.” When you abjure something, you are formally stepping away from it, renouncing it.
• Remember adjure by thinking of “address” or “advocate.” The prefix “ad-” means “to” or “toward.” When you adjure someone, you are directing a solemn request or command to them.
