Morphology

third + deck

The meaning is directly and transparently derived from combining 'third' (ordinal number three) with 'deck' (a ship platform): it simply denotes the deck in the third position. This ordinal+noun composition is a regular, cross‑linguistic pattern with no idiomatic shift, so a B1 learner who knows both words can infer the meaning.

Etymology

Third deck comes from old ships with many levels. The phrase names the third deck down, a lower level where sailors slept or cargo was kept, so it means 'the deck located below the main deck'.
