Surface Forms

Morphology

flat + on + one + back

The meaning 'lying with one's back against a surface' is directly compositional from 'flat' (level/even) + locative 'on' + possessive 'one's' + 'back' (rear surface). This straightforward locative image follows normal English grammar and appears in many languages, so a B1 learner who knows the component words would readily infer the meaning.

Etymology

Flat on one's back shows a clear picture: a person is lying completely flat with their back on the ground or a bed and cannot get up easily. That's why it means 'lying down because you are resting, hurt, or sick'.
