Homographs are at least two words that are spelled exactly the same but have different meanings and sometimes different pronunciations, such as "moped," the past tense of mope or a type of motorbike. Another example is the word "bear," which either means to carry or a large wild animal.
One example of a homograph is the word "fair", which either means a pleasant appearance or a large outdoor event. Another word that is spelled and pronounced the same is "hide," and it has three distinct meanings. "Hide" refers to an animal skin, a section of land or the act of concealing something. The word "hops" means either the act of jumping or an ingredient in many types of beer.
"Sewer" is a word that has multiple pronunciations but is spelled the same. It either means a person who sews or a means of transporting water and waste. A similar word is "tear," which either means a rip or a liquid substance produced by the eyes. The word "wind" means either moving air or to wrap or turn. The past tense of the second meaning, "wound," also means a cut or injury.
Homographs are a type of homonym and come from the Latin words that mean "to write the same." They are similar to heteronyms and homophones. Homographs are often used in puns and limericks because their dual meanings create interesting sentences.
