Morphology

run + out + of + steam

The pattern 'run out of' is productive and clearly signals depletion, and combining it with 'steam' invites a metaphorical reading of 'steam' as energy or momentum (cf. 'full steam ahead'). Because the metaphoric shift from literal vapor to 'energy/enthusiasm' is conventional in English but not strictly literal, a B1 learner who knows the words can often infer the meaning from context but may still need prior exposure, so the item is only partially transparent.

Etymology

The idiom run out of steam comes from old steam engines. When an engine had no steam left it could not move, so to run out of steam came to mean 'to lose energy or motivation'.
