Definition of the word bin liner

The term "bin liner" is a British English expression used to describe a plastic bag that is typically used to contain household waste and line inside of the garbage bin. The phrase "bin liner" came into use during the 1960s when these bags first became widely available as a convenient and hygienic alternative to simply throwing trash directly into bins. The term is a compound word that combines two elements: "bin," which is derived from the Middle English word "bynne" meaning "container," and "liner," which refers to the bag's function of lining the bin and preventing direct contact between the waste and the bin itself. The popularity of this term in British English can be attributed to the fact that it is a concise and practical phrase that accurately describes the item's function. Alternative terms for these bags in American English include "trash bags" or "garbage bags."
