Morphology

lower + bound

The meaning is directly compositional: 'lower' specifies the direction/side of the 'bound' (a limit), so a learner who knows both words can infer it refers to the limit on the low side of a set. The construction follows common modifier+noun logic and is cross-linguistically transparent, so the mathematical specialization does not block derivation from the parts.

Etymology

The term lower bound is like a floor under a group of numbers: lower means the bottom and bound means a limit that stops things from going down. So it means a value that is 'no smaller than' any number in the set.
