A spoon is type of cutlery which is used for eating. It is characterized by its smooth concave surface (from the eater's point of view), which is usually called the "bowl".
Types
There are various types of spoons, including soup spoons (a mid-size spoon with a round bowl), dessert spoons (a mid-size spoon with an oval bowl), serving spoons (a large usually oval spoon used for conveying food from a serving dish to a plate or bowl), teaspoons (small oval spoons), coffee spoons (even smaller oval spoons), egg spoons (often made of horn), grapefruit spons (an oval spoon with a deep bowl and a sharp edge), and jam spoons (which have cutaways like a violin on each side of the bowl).
Other Uses
A spoonerism is created when a speaker switches the consonants between two words. For example: "shake a tower" as a substitution for "take a shower." The Shel Silverstein book Runny Babbit is another famous example.
