il·i·um

, pl.

il·i·a

(il'ē-ŭm, il'ē-ă), [TA] Do not confuse this word with ileum.
The broad, flaring portion of the hip bone, distinct at birth but later becoming fused with the ischium and pubis; it consists of a body, which joins the pubis and ischium to form the acetabulum and a broad thin portion, called the ala or wing, bordered superiorly by a thicker crest. The body transmits the weight of the trunk to the femur, whereas the ala and crest provide for muscle attachment and protect abdominopelvic viscera.
[L. groin, flank]
