Tandie \t(a)-ndie, tan-die\ as a boy's name (also used as girl's name Tandie). Modern name, possibly derived as a Scottish nickname for Andrew. However, the Latin-derived English word "tandem" could also be a source, as well as the Old Norse term "tandr", meaning "fire". The name could also be derived from the Zulu name Thandiwe or from the name of an Irish patriot, James Napper Tandy, whose exploits are featured in the ballad "The Wearing of the Green".
