The word "apenteric" is spelled /eɪˌpɛntəˈrɪk/. It is derived from two Greek words: "a" meaning "not" and "enteron" meaning "intestine". Thus, "apenteric" refers to something that does not have an intestine. This rare medical term is used to describe certain animals, such as the echidna, which do not have a true stomach or intestinal system. Although the spelling may seem complex, the word is pronounced as it is spelled with emphasis on the second and fourth syllables.
Away from the intestine, said of an infection or a morbid process usually taking place there.
