Morphology

ischial + bone

The phrase is directly compositional: 'ischial' specifies the location/relationship to the ischium (the lower, posterior part of the hip) and 'bone' names skeletal tissue, so the expression denotes the bone in that area. This adjectival + noun location pattern is regular and predictable, so a learner who already knows both constituents would understand the meaning.

Etymology

Ischial bone comes from an old Greek word 'ischion' that meant the hip or the part you sit on. Because this bone makes the lower, back part of the pelvis and bears weight when you sit, the name now refers to the bone under your bottom that supports you.
