Morphology

back + end

The sense of 'back end' as the rear/behind part of a system is directly compositional from 'back' (rear) + 'end' (part/segment), so a learner who knows those words can infer it refers to the behind/rear part of an application. The spatial 'front/back' metaphor for system parts is cross-linguistically common (and widely used in computing), making the basic meaning accessible to a B1 learner even if they lack detailed technical knowledge.

Etymology

Back end in computer work comes from the idea of the back of a machine or building where the work is done out of sight. So the back end of an app is the hidden part that stores data and does the work behind the screen, which is why it means the 'server-side' of a system.
