Morphology

trailing + edge

The meaning 'rear edge' is directly derivable from 'trailing' (following/at the back) combined with 'edge' (boundary), so the compound transparently denotes the back/border part of an object. This is a regular compositional pattern and a B1 learner who knows both constituents can reasonably infer the MWE's meaning even if they haven't seen the technical aeronautical context.

Etymology

Trailing edge comes from the simple image of trailing meaning 'following' and edge meaning the outer part of a wing, so it refers to the 'back' or 'rear' edge of a wing or blade today.
