Morphology
The phrase is transparently built from 'boundary' (an edge or limit) + 'layer' (a stratum), so a learner can infer it refers to a layer at a boundary or surface. However, the precise technical sense (a very thin region in fluid dynamics with slowed flow due to friction) requires domain knowledge, so the meaning is only partially predictable from the constituents.
Etymology
Boundary layer names the thin layer of air or water that sits at the boundary right next to a surface and moves more slowly because it rubs against that surface. Think of air along a wing or dust near the ground: the slowed 'layer' changes heat and movement, so engineers study the boundary layer to understand and improve performance.
