Ruppa in ruppa -- rūpakaŋ (nt.) Th 2, 394 is not clear. It refers to something which is not rūpa, yet pretends to be rūpa, i. e. a sham performance or show. Thus ruppa may correspond to *rūpya & with rūpaka mean "having the form (i. e. the appearance) of form, i. e. substantiality. " The Cy. (ThA 259) interprets as "rūpiya -- rūpasadisaŋ sāraŋ sāraŋ upaṭṭhahantaŋ asāran ti attho"; and Mrs. Rh. D. (Sisters, p. 154) trsls: "deluded by puppet shows (seen in the midst of the crowd)."
