Morphology

once + and + for + all

The components 'once' (one time) plus 'for all' (for everything/for all time) produce a recognisable compositional logic of a single act that applies permanently, and many languages have similar calques, so part of the meaning can be inferred. However, the precise idiomatic force of 'finally and completely settle' is not fully predictable from the words alone for an average B1 learner without prior exposure, so it is only partially transparent.

Etymology

Once and for all comes from the simple idea of doing something one time (once) so it is finished for everyone and always (for all); imagine fixing a leak once so it never happens again. That's why it means 'finally' and 'completely'.
