（Chambers）to promise solemnly, especially under oath, to stop believing or doing something
（Collins Cobuild）If you abjure something such as a belief or way of life, you state publicly that you will give it up or that you reject it.
（近義字辨析）abjure的靈魂涵義就是under oath，並帶有堅決的態度，MW第二定義的abstain from稍沒那麼常用，還是以第一定義為重；renounce可能有否認、聲明斷絕的涵義；forswear有偽證、背信的暗示；recant強調收回或否認先前所稱；retract指收回承諾、提議或指控。
（古語）abjure the realm（誓不回國：swear an oath to leave a country forever）
