(Russian) short form of Zinaida (from Greek Zēnais, a derivative of the name of the god Zeus), the name of an obscure saint venerated in the Eastern Church. It is also a Russian short form of the rarer given name Zinovia (from Greek Zēnobia, a compound of Zeus + bios ‘life’). Its adoption as a given name in the English-speaking world probably owes something to its resemblance to the popular girl's name Tina.
English, Scottish, and northern Irish: occupational name for a maker of machinery, mostly in wood, of any of a wide range of kinds, from Old English wyrhta, wryhta ‘craftsman’ (a derivative of wyrcan ‘to work or make’). The term is found in various combinations (for example, Cartwright and Wainwright), but when used in isolation it generally referred to a builder of windmills or watermills.
