Morphology

tracheal + gill

The compound is a straightforward adjective + noun where 'tracheal' (related to the tracheae) modifies 'gill' (a breathing organ), so the overall meaning—a gill associated with the tracheae used for respiration—is directly inferable from the parts. Although somewhat technical, the composition is literal and follows normal English formation patterns, so a learner who knows both constituents will understand the MWE.

Etymology

Tracheal gill names a thin, leaflike part on some insect larvae that helps them 'breathe underwater'. The word tracheal points to the insect's breathing tubes and gill shows a thin water organ, so the image is a tube-connected leaf that lets the insect get oxygen from the water.
