spar (n.2) Look up spar at Dictionary.com
"crystalline mineral that breaks easily into fragments with smooth surfaces," 1580s, from Low German Spar, from Middle Low German *spar, *sper, cognate with Old English spær- in spærstan "gypsum."
spar (n.1) Look up spar at Dictionary.com
early 14c., "rafter;" late 14c., "stout pole," from or cognate with Middle Low German or Middle Dutch sparre, from Proto-Germanic *sparron (cf. Old English *spere "spear, lance," Old Norse sperra "rafter, beam," German Sparren "spar, rafter"), from PIE root *sper- (1) "spear, pole" (see spear (n.1)). Nautical use, in reference to one used as a mast, yard, boom, etc., dates from 1630s. Also borrowed in Old French as esparre, which might be the direct source of the English word.
