Morphology
The meaning 'one of the main long feathers on the outer edge of a bird's wing' is directly derivable from combining 'primary' (main/first) with 'feather' (a bird's plume). This simple adjective+noun compositional pattern is cross-linguistically common and would be understandable to a B1 learner who knows both constituents.
Etymology
Primary feather is a simple name from watching birds: primary means 'main' or 'first' and feather is a bird's feather. These long feathers at the outer edge of the wing are the main ones used for 'flight', so the name explains their job.
