Morphology

tarsometatarsus = tarsus + metatarsus (transparent) = tarso + metatarsus

The term names the fused tarsal and metatarsal regions; a learner familiar with the anatomical terms can infer this.

Etymology

Tarsometatarsus comes from two bone names: tarsus ('ankle' or 'flat of the foot') and metatarsus, where meta- means 'after'. The name describes the bone made when the ankle bones and the bones 'after the ankle' join, so it tells you where this bone is and why it helps support a bird's lower leg.
