Alternative forms

  • ilion (4th to 7th centuries)

Etymology

Borrowed from Latin īlium (“lower abdomen”), from īle (“flank”).

Pronunciation

Noun

ilium (plural ilia)

  1. (anatomy) The upper and widest of the three bones that make up each side of the hipbone and pelvis.
  2. (anatomy, obsolete) The ileum, part of the small intestine (in modern usage, misspelling of ileum.).

Usage notes

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:

  • There is an -i- in the middle of both ilium and hip.
  • The two letters i in ilium look like bones whereas the -e- in ileum is squiggly like an intestine.
  • The intestinal obstruction called ileus affects the ileum, and both have an -e-.
