Morphology

first + in + first + out

The phrase literally assembles the meanings of its parts: the earliest items that go “in” are the earliest to come “out,” so the system’s ordering is directly predictable from the constituents. This compositional pattern is cross-linguistically and conceptually transparent (used in everyday contexts like queues or lines), so a B1 learner who knows 'first', 'in', and 'out' will readily infer the meaning.

Etymology

First in first out comes from a simple image of a line or a store shelf where the thing that goes in first is taken out first. So, it means 'the first item to arrive is the first to be used, sold, or processed'.
