Morphology

on + purpose

The phrase combines 'purpose' (reason/intention) with the preposition 'on' to yield the sense 'with purpose' or 'intentionally', so the overall meaning is directly inferable from its parts. This compositional pattern is cross-linguistically common (e.g., Spanish 'a propósito', French 'exprès/à dessein'), so a B1 learner who knows the constituents would typically understand it.

Etymology

On purpose comes from the simple idea of doing something with a clear aim, being on a chosen purpose. Imagine aiming at a target and hitting it 'on purpose'—that's why it means 'intentionally', not 'by accident'.
