Forms

tremper[1] Old and Middle French temprer, tenprer;[2][3][4] tremper by metathesis from the early 13th century.[2][3][4]

Etymology

It is inherited from Old French temprer, inherited from Latin temperō (“to mix in due proportion, to moderate”).[2][3][4][5] The ⟨r⟩ moved by metathesis, giving the present form from the early 13th century, and the new form soon drove out the old.[3][6] Gregory of Tours already writes vinum temperatum of wine mixed with water.[6] The Latin verb is probably derived from tempus (“time”).[7][8]

Compare Occitan trempar, Catalan trempar, Spanish templar, Portuguese temperar and Italian temprare.[7][9] tempérer is a learned borrowing of the same Latin verb, and the two families shared out its senses: the borrowing took “to moderate”, the inherited verb “to soak, to dilute”.[3][7]

Earliest recorded meaning

The old form temprer is first recorded about 1155 in Wace's Brut, of softening the water of a bath; in the 12th–14th centuries it meant to mix, to moderate, to temper metal and to dip into a liquid.[2] A 12th-century poem says of a helmet qui si fu dur tenprez, so hard was it tempered.[9]

Semantic evolution

The sense “to mix wine with water” was inherited from Latin and survives only in tremper son vin (Joinville, 1306); Joinville says of Saint Louis that son vin trempoit par mesure.[2][3][9] From it came “to soak with a liquid” (1213), as in tremper la soupe (1547), to pour broth over slices of bread, and the old slang sense “to eat” (1867).[3][2] The intransitive “to stay in a liquid” is recorded from the 13th century.[3]

From the 12th century the verb meant to plunge hot steel into cold water to harden it (tremper l'acier), and in 1613 Régnier has esprit trempé, a mind steeled by trials.[6][3][2] Figuratively tremper dans (1640) is to be involved in a shady affair, hence tremper dans le sang (Racine, 1677).[3][2] In the Middle Ages it could also mean to tune a harp.[6] Popular speech used it for “to beat” (1867), and tremper sa chemise (mid-20th century) is to work very hard.[3]
