'machine-washable' originates from the combination of 'machine' and 'washable', where 'machine' refers to a mechanical device and 'washable' means capable of being washed.

'machine-washable' evolved from the need to describe fabrics that could withstand the mechanical action of washing machines, a concept that became more prevalent with the rise of household appliances in the 20th century.

Initially, it meant 'capable of being washed by hand or machine', but over time it evolved to specifically mean 'suitable for washing in a machine'.
