late Middle English (sense 2): from French, from Italian carato, from Arabic ḳīrāṭ (a unit of weight), from Greek keration 'fruit of the carob' (also denoting a unit of weight), diminutive of keras 'horn', with reference to the elongated seedpod of the carob.
This measure of the purity of gold and a unit of weight for precious stones comes via French from Italian carato, from Arabi kīrāţ, a unit of weight. The base is Greek keration used for both a carob seed and a unit of weight but literally ‘little horn’ describing the carob's elongated seedpod.
