farrago: [17] The notion of a farrago being a ‘heterogeneous mixture’ comes originally from the mixture of various grains for animal feed. Latin farrāgo was a derivative of far ‘corn’ (source of English farinaceous [17] and related to barley and barn), and was extended metaphorically to ‘medley, hotch-potch’ in classical times. => barley, barn, farinaceous[farrago etymology, farrago origin, 英语词源]
