The shilling is a unit of currency formerly used in the United Kingdom and other British Commonwealth countries. The word shilling comes from scilling, an accounting term that dates back to Anglo-Saxon times where it was deemed to be the value of a cow in Kent or a sheep elsewhere. The word is thought to derive from the base skell-, "to ring/resound" and the diminutivesuffix-ling. Slang terms for the old shilling coins include "bob" and "hog".

The abbreviation for shilling is s, from the Latin solidus, the name of a Roman coin. Often it was informally represented by a slash, standing for a long s or ſ, thus 1/6 would be 1 shilling and sixpence, often pronounced "one and six".
