Morphology

foot-lambert = foot + lambert (transparent) = foot + lambert

Formed by straightforward compounding of two unit names; as a compound unit its meaning (a measure of luminance) is directly derivable from the component units.

Etymology

Foot-lambert joins foot ('a unit of length') and Lambert (the name of a scientist who studied light). So foot-lambert means the 'brightness' of a surface measured for each square foot.
