Morphology

sacroiliac = sacrum + iliac (transparent) = sacro + iliac

Built by combining sacro- (sacrum) and iliac to denote the joint between those bones, so the relation is direct for those who know the anatomical bases.

Etymology

Sacroiliac comes from Latin parts sacro- (from sacer, 'sacred') and -iliac (from ilium, 'hip'). A helpful way to remember is that the 'sacred' sacrum meets the hip bone, so sacroiliac describes something related to the joint where those bones join.
