Morphology

lower + berth

The meaning 'the bottom bed' is directly and compositionally derived from 'lower' (indicating the more low/bottom position) modifying 'berth' (a built-in bed), so a learner who knows both words can infer it. This adjective+noun pattern is common cross-linguistically and follows ordinary English composition, making the expression immediately comprehensible to B1 learners.

Etymology

Lower berth comes from trains and ships where two 'sleeping places' are placed one above the other. The lower bed is the bottom one and the berth is the 'sleeping place', so lower berth means the bottom bed that is easier to climb into.
