wig: [17] Wig is short for periwig [16], which in turn is an alteration of perwike, a now defunct variant of peruke [16]; and peruke came via French perruque from Italian perrucca, a word of unknown origin. Wigging ‘scolding’, first recorded at the beginning of the 19th century, may have been inspired by the notion of being told off by a bigwig [18], etymologically a ‘highranking bewigged dignitary’. => periwig, peruke[wig etymology, wig origin, 英语词源]
