Old English māsc (used as a brewing term); perhaps ultimately related to mix.

  • Brewing provides the earliest context of mash. The mash is a mixture of ground malt and hot water which is left to stand to form the infusion called ‘wort’. The first example of mash meaning ‘mashed potatoes’ is from 1904, by the British MP and novelist A. E. W. Mason: ‘I…go into a public-house…and have a sausage and mash and a pot of beer.’ The word may ultimately be related to mix. This is from Latin mixtus which became mixte in Old French. This was heard by English speakers as ‘mixed’ and a new verb, to mix, was formed. As an abbreviation for ‘mobile army surgical hospital’ MASH goes back to 1950. The term was made famous in the 1970 film M*A*S*H, set in a field hospital during the Korean War. The film gave rise to a long-running TV series ( 1972–83).
