testy: [14] Testy means etymologically ‘heady’. It was borrowed from Anglo-Norman testif, a derivative of Old French teste ‘head’ (ancestor of modern French tête). This in turn went back to Latin testa ‘tile, earthenware pot’ (a relative of testum, from which English gets test), which in the post-classical period was used humorously for ‘head’. English acquired testy in the sense ‘headstrong, impetuous’, but by the 16th century it had shifted via ‘impatient’ to ‘irritable’.
