(qep'a' 24 New Words): So if you have a scar that you got in a fight, that could be either a mIvwa' or a SanDIy. If you don't know whether someone's scar resulted from a wound or a disease, it's probably safest to go with mIvwa'. If the person's scar is actually a SanDIy, he/she will, under most circumstances, clarify this for you. If it's a roptoj, he/she may let the "misdiagnosis" slide since, as we all know, ropchoHbe' tlhInganpu'." KLI Source
