Etymology

It is inherited from Middle English morter, partly inherited from Old English mortere, borrowed from Latin mortārium (“a vessel for pounding; the material pounded in it”),[2][3][4][5][6] and partly reborrowed from Anglo-Norman and mortier, of the same Latin origin;[2][5][7] the English spelling was later brought into line with the Latin.[8][9] Hoad and the Shorter Oxford also see a share of Middle Low German mortēr.[8][7] The Latin noun is of uncertain origin:[10][11] Watkins and Barnhart derive it from an Indo-European root meaning to rub away or pound,[10][4][5] Klein from a participle Proto-Indo-European *mr̥tós (“rubbed, pounded”),[6] and Merriam-Webster compares Ancient Greek μαραίνω (maraínō, “to waste away”), relating it to smart.[3] The same Latin word gave Old High German mortāri and German Mörser.[6][12] The cannon is mortier, the same word, named for its squat shape like a pounding bowl.[5][10][8][11]

Earliest recorded meaning

A bowl of hard material in which substances are pounded with a pestle: early Old English, in the Cleopatra Glossary,[2] about 1000 in Barnhart and before the 12th century in Merriam-Webster.[5][3] The form morter is recorded about 1150, and mortar in 1381.[5] Anglo-Norman mortier had the same sense from the late 12th century.[13]

Semantic evolution

The pounding bowl was a tool of the apothecary and the cook,[2] and was used figuratively from the Wycliffite Bible on (a1382).[2] Like the Anglo-Norman word, Middle English mortar also named a bowl of wax or oil with a floating wick, used as a night light (a1398–1894).[2][13][3] From 1547 the word named a short, wide-bored piece of artillery that throws shells at a high angle,[2] first called a mortar-piece (1550s),[10][5] by comparison of its shape with the bowl;[10][11][12] it was later used of any device firing a projectile on a high trajectory, such as a firework or a lifeline (1669).[2] Johnson (1755) gave both the pounding vessel and the short cannon for bombs.[14] The verb to mortar, to fire mortar shells at, is recorded from 1944.[2][3] In 18th- and 19th-century slang the bowl, with its pestle, served as a sexual double entendre.[15]

Etymology

It is inherited from Middle English morter, borrowed from Anglo-Norman morter and mortier (“builder's mortar; mixing bowl”),[2][10][5][3][7] partly also taken directly from Latin mortārium,[2][10] the same word as the pounding bowl, with the sense transferred from the vessel to the material prepared in it, as already in Latin.[2][10][7][6] Ayto and Cresswell explain the transfer by the grinding of the ingredients.[11][16] Dutch mortel and German Mörtel are from Latin or French.[10][6][12]

Earliest recorded meaning

A mixture of lime, sand and water used to bind stones or bricks: about 1250 in Barnhart and Etymonline,[5][10] the OED's first quotation from Floris and Blauncheflur (a1300).[2] The Anglo-Norman Dictionary records builder's mortier in Anglo-Norman from the second quarter of the 12th century.[13]

Semantic evolution

Figurative uses, of something that binds or holds together, are recorded from Langland's Piers Plowman (about 1400),[2][3] and the extended sense of plaster or any mortar-like substance from 1440.[2] From 1582 to 1798 the word could stand for building or masonry in general.[2] The verb, to plaster or join with mortar, is recorded from 1610, in a figurative passage by Donne.[2] The phrase bricks and mortar, for buildings as property, is listed by the Shorter Oxford.[7] In Scotland the word named a coarse red clay, and in Northamptonshire a mortar-spit was the board holding the mortar; in Nottinghamshire and Lincolnshire to mortar meant to tramp mud about with dirty feet.[17][3]

  • c. 1250 – builder's mortar.[5][10]
  • c. 1400 – figurative, a binding force.[2]
  • 1440 – plaster or a similar substance.[2]
