Morphology

subproblem = problem (transparent) = sub + problem

The meaning is directly derived from the productive prefix 'sub-' meaning 'part/under' plus 'problem', yielding 'a smaller part of a larger problem'.

Etymology

The word subproblem begins with sub-, meaning 'under' or 'below', and ends with problem. A helpful image is a submarine under the sea: 'sub-' shows something is beneath or part of a larger thing, so a subproblem is a smaller problem that belongs to a bigger problem and is easier to solve on its own.
