Morphology

to + the + bitter + end

The phrase combines 'bitter' (unpleasant, harsh) with 'end' (final point) and the preposition 'to' signaling extent, so its sense of persisting until an unpleasant or final point is directly inferable from the parts. This compositional metaphor is common across languages and follows normal adjective+noun and prepositional patterns, making it accessible to a B1 learner who knows the constituent words.

Etymology

The idiom to the bitter end may come from old ships. Sailors tied a rope to a wooden post called 'bitts', and when only the last bit of rope reached that post it was the bitter end. So, the phrase came to mean 'to keep going until the very end'.
