Borrowed from Latin īlium (“lower abdomen”), from īle (“flank”).
In modern usage, the spelling ilium always refers to the bones of the hip and pelvis whereas the spelling ileum always refers to the last part of the small intestine. To remember the different spellings of these identically pronounced words, people have come up with the following mnemonics, for example:
