Sense: idiom/1

While all three expressions describe completing a task, to the bitter end carries the strongest connotation of suffering or resistance — it implies the ending itself is painful or hard-won. See something through is the most neutral; you can use it for completing a project, a course, or a promise without implying pain. Stick it out is informal and suggests mild-to-moderate discomfort, like finishing a boring movie or a tough semester. Go the distance comes from boxing and is used for meeting a demanding challenge, often in sport, business, or endurance contexts. For example: 'Maya saw the training programme through even though it was hard' (neutral); but 'Maya fought to the bitter end against the disease' (implies grave struggle).

Etymology

Old Englishnautical EnglishModern English

This phrase has nautical origins. On sailing ships, the 'bitter end' referred to the part of an anchor cable that was fastened to a pair of posts on deck called the 'bitts.' When the entire cable was paid out — to the bitter end — no more rope remained. By the 1800s, the expression had broadened to mean pushing any situation as far as possible, eventually taking on the modern sense of enduring hardship to the finish.
