Morphology
The noun phrase is partly compositional: a learner who knows 'closed' (not open/finite) and 'universe' can infer a general idea of a universe that is somehow 'closed' or limited. However, the specific cosmological sense (spatially closed geometry, enough matter to halt expansion and cause contraction) is technical and not fully predictable from the basic words alone, so learners would grasp only a vague idea without prior exposure.
Etymology
The term closed universe comes from imagining space as a closed shape, like the surface of a ball where you could keep walking and come back to the same place. That image of closed space helps explain why it means a universe that may 'stop expanding' and then turn back on itself or 'collapse'.
