Morphology

footwall = foot + wall (semi-transparent) = foot + wall

The components 'foot' and 'wall' are literal, but the term is a domain-specific geological label (lower side of a fault) and may not be predictable to general learners.

Etymology

Footwall comes from the simple parts foot and wall. Think of 'foot' as the 'bottom' or 'base' and 'wall' as a 'side', so a footwall is the lower or bottom side of a fault.
