Abjure - adjure
From Hull AWE
These are two words with similar derivations, but very different meanings - almost opposite to each other. The stress is on the second syllable in both cases, and they can be hard to tell apart in speech - though they are not homophones.
- To abjure something is '˜to swear not to do it', or 'to give it up': "because of my hangover, I abjure alcohol." In more historical contexts, one could abjure a belief or a loyalty: "In swearing allegiance to the Catholic King, he was in effect abjuring his protestant beliefs."
- 'To adjure' on the other hand is to persuade, charge or entreat solemnly or earnestly (as if under oath or under the penalty of a curse) as in: "I adjure all students to avoid the crime of plagiarism."
