Etymology (EN): O.E. organe, from O.Fr. orgene “musical instrument,” from L. organa, pluriel of organum, from Gk. organon “implement, musical instrument, organ of the body,” literally “that with which one works,” from PIE *werg-ano-, from base *werg- “to do, to work” related to Gk. ergon “work” (cf. Av. varəz- “to work, do, perform, exercise;” Mod.Pers. varz-, varzidan “to labor, exercise, practise;” Arm. gorc “work;” Lith. verziu “tie, fasten, squeeze,” vargas “need, distress;” Goth. waurkjan; O.E. wyrcan “work,” wrecan “to drive, hunt, pursue”).

Etymology (PE): 1) Andâm, from Mid.Pers. handam “member, limb;” Av. handāma- “limb;” from Proto-Iranian *ham-dāman-, from prefix ham-→ com- + *dāman- “created;” Av. dā- “to give, grant; to put; to create; to determine” (O.Pers./Av. dā- “to give, grant, yield,” dadāiti “he gives;” Mod.Pers. dâdan “to give;” cf.
Skt. dadáti “he gives;” Gk. tithenai “to place, put, set,” didomi “I give;”
L. dare “to give, offer,” facere “to do, to make;” Rus. delat’ “to do;” O.H.G. tuon, Ger. tun, O.E. don “to do;” PIE base *dhe- “to put, to do”); cf. Skt. sandháy- “joint, articulation.”
