Morphology

tail + fin

The meaning 'the fin at the tail of an aircraft' is directly derivable from combining 'tail' (rear part) with 'fin' (an appendage), so a B1 learner who knows both words can infer it denotes an appendage at the rear used for stability. This noun–noun compounding follows a common, compositional pattern and the extension of 'fin' to non‑aquatic appendages is conceptually transparent across languages.

Etymology

Tail fin The vertical fin at the back of a plane acts like a small tail that keeps the plane pointing straight and helps control direction, so tail fin means the stabilizing surface at the tail of an aircraft.
