A toy is an object used in play. Toys are usually associated with children and pets, but it is not unusual for adult humans and some non-domesticatedanimals to play with toys. Many items are manufactured to serve as toys, but items produced for other purposes can also be used as toys. A child may pick up a household item and 'fly' it around pretending that it is an airplane, or an animal might play with a pinecone by batting at it, biting it, chasing it, and throwing it up in the air. Some toys are produced primarily as collector's items and are not intended to be played with.
The origin of toys is prehistoric; dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are readily found at archaeological sites. The origin of the word "toy" is unknown, but it is believed that it was first used in the 14th century.
Toys and play in general are an important part of the process of learning about the world and growing up. The young use toys and play to discover their identity, help their bodies grow strong, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults use toys and play to form and strengthen social bonds, teach, remember and reinforce lessons from their youth, discover their identity, exercise their minds and bodies, explore relationships, practice skills, and decorate their living spaces.

A puzzle is a problem or enigma that tests the ingenuity of the solver. In a basic puzzle, one is intended to put together pieces in a logical way in order to come up with the desired solution. Puzzles are often contrived as a form of entertainment, but they can also stem from serious mathematical or logistical problems — in such cases, their successful resolution can be a significant contribution to mathematical research.
