Morphology
The combination 'wall' + 'plate' gives a clear hint that this is a flat element associated with a wall (so learners can infer a panel or piece attached to a wall), but the specific technical sense — a horizontal timber at the top of a wall that supports joists or rafters and distributes load — is specialized and not fully derivable from the constituents. Because the structural function and timber sense of 'plate' are domain-specific and require prior exposure, the expression is only partially predictable to a B1 learner.
Etymology
The compound noun wall plate comes from building work. A long, flat piece of wood called the plate sits on top of a wall to 'support' the roof or floor and to 'share' their weight, so the name means the board that holds and spreads the load.
