Morphology

retractable + dome

The meaning is directly compositional: 'retractable' (able to be pulled in or withdrawn) modifies 'dome' so a B1 learner who knows both words can infer a dome that can be opened, closed, or pulled back. This adjective+noun combination follows a common and cross-linguistically transparent pattern, so the overall sense is immediately derivable from the parts.

Etymology

Retractable dome uses retractable (meaning 'able to be pulled back') and dome (a round roof), so picture a big round roof that can slide away like a car sunroof. That's why it means a dome that can be 'opened' or 'closed' by a machine.
