In sports, a loan involves a particular player being able to temporarily play for a club other than the one to which they are currently contracted. Loan deals may last from a few weeks to a full season, sometimes persisting for multiple seasons at a time. A loan fee can be arranged by the parent club as well as them asking to pay a percentage of their wages.

Association football was first codified in 1863 in England, although games that involved the kicking of a ball were evident considerably earlier. A large number of football-related terms have since emerged to describe various aspects of the sport and its culture.
