Morphology

split + up

The verb 'split' conveys division and the particle 'up' commonly adds a sense of separation or increase, so a learner who knows both words could infer this is about dividing something into more parts (i.e. shares). However, the specific financial nuance that the total equity/value remains unchanged despite increasing the number of outstanding shares is technical and not fully predictable from the constituents alone, so the phrase is only partially transparent to a B1 learner.

Etymology

Split up meaning to end a relationship comes from the picture of two people who were together suddenly moving apart. The pair 'split' into parts and go their own ways, so the phrase means 'to end a relationship'.
