ERCP is a combination of two tests: an endoscopy and an X-ray. An endoscopy is a procedure in which a thin, flexible tube attached to a tiny camera is threaded down to your gastrointestinal (GI) tract. Your GI tract consists of your esophagus, stomach, and intestines.
HOMOGRAPHS are words that are spelled the same but have different meanings. Heteronyms are a type of homograph that are also spelled the same and have different meanings, but sound different. WORDS THAT BOTH SOUND THE SAME AND ARE SPELLED THE SAME are both homonyms (same sound) and homographs (same spelling). Example: lie (untruth) and lie (prone); fair (county fair), fair (reasonable).
However, lead, pronounced LED, means a metallic element. Compare heteronyms to homographs, homophones, and homonyms. Homographs are words that are spelled the same but differ in meaning, derivation, or pronunciation. Homophones are words that are pronounced the same but differ in meaning, derivation, or spelling. Homonyms are words that are spelled and pronounced the same but have different meanings. There is overlap among these categories. Heteronyms are specific types of homographs in which the different pronunciations are associated with different meanings.
