Morphology

push-down + queue

While the words 'push' and 'down' are individually transparent and 'queue' is familiar, the combined form 'push-down queue' denotes a technical LIFO (last-in, first-out) behavior that a B1 learner would not reliably infer from literal meanings alone. The phrase partially hints at a stacking action (push + down) so there is some cueing, but understanding the specific removal order requires prior technical exposure.

Etymology

Push-down queue comes from a simple pile image. Imagine a stack of plates where you push a new plate down on top of the pile; the last plate put on is the first one you take off. So a push-down queue means 'last in, first out', the newest item leaves first.
