Morphology

rock + out

The element 'rock' clearly signals the music genre so a learner can infer the expression relates to performing or enjoying rock music, but the particle 'out' does not literally mean 'with great energy' — it functions as a colloquial intensifier in phrasal verbs. Because the overall sense depends on knowing this phrasal use of 'out' (not directly predictable from the literal meanings), the expression is only partially transparent to a B1 learner.

Etymology

Rock out comes from rock music: rock means to play or move with strong beats and out gives the idea of going all the way or going wild. So, rock out means 'to perform or enjoy music with great energy'.
