To the bitter end is an idiom with a disputed etymology. We will examine the meaning of the expression to the bitter end, some possible sources of its origin, and some examples of its use in sentences.
To the bitter end means to complete something no matter how unpleasant or stressful it is to accomplish, to see something through to the end, even though the ending may be unpleasant. To the bitter end implies a commitment to fulfilling a responsibility, to doing a dirty job that no one else wants to do, to persevering in the face of adversity. There are two schools of thought concerning the origin of the idiom to the bitter end. Some believe that the phrase is adapted from a passage in the bible, translated in the King James Version in 1611: “For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil: But her end is bitter as wormwood, sharp as a two-edged sword.” (Proverbs 5:3) Others trace the origin of the phrase to the bitter end to a nautical term, which was included in a lexicon called Seaman’s Grammar, published in 1627 by John Smith: “A Bitter is but the turne of a Cable about the Bits, and veare it out by little and little. And the Bitters end is that part of the Cable doth stay within boord.” Neither use of the phrase to the better end is the same as today’s meaning, which first occurred in the 1830s.
