Morphology

time + machine

The compound 'time machine' is directly interpretable as a 'machine' that acts on or manipulates 'time', so a learner who knows 'time' and 'machine' can infer it refers to a device related to time (typically for traveling or manipulating time). This compositional pattern is common across languages and in fiction, making the meaning immediately accessible to a B1 learner without prior exposure.

Etymology

The compound noun time machine may come from H. G. Wells's story 'The Time Machine', where a small machine carries a person through time to the past or future. That's why the phrase means 'a device that lets someone go to the past or future'.
