Anglicized form of Carolus (see Charles), or of its feminine derivative Carola. It has never been common as a boy's name, and has become even less so since its growth in popularity as a girl's name. This seems to be of relatively recent origin (not being found much before the end of the 19th century). It probably originated as a short form of Caroline.
English and Scottish: 1. mainly a topographic name for someone who lived in or by a wood or a metonymic occupational name for a woodcutter or forester, from Middle English wode ‘wood’ (Old English wudu). 2. nickname for a mad, eccentric, or violent person, from Middle English wōd ‘mad’, ‘frenzied’ (Old English wād), as in Adam le Wode, Worcestershire 1221.
