Shilling
The shilling is a unit of currency used in some current and former British Commonwealth countries. The word shilling comes from scilling, an accounting term that dates back to Anglo-Saxon times where it was said 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 diminutive suffix -ling. The slang term for a shilling as a currency unit was a "bob".
