According to Wikipedia, “A homophone is a word that is pronounced the same as another word but differs in meaning. The words may be spelled the same, such as rose (flower) and rose (past tense of “rise”), or differently, such as carat, caret, and carrot, or to, two, and too. Homophones that are spelled the same are also both homographs and homonyms.”

Here’s a test. See how you fare.

Note: The person who has devised this test has called it homonyms, but according to the Wikipedia definition, these are homophones.
