θέσις

From τίθημι (títhēmi, “I put, place”) +‎ -σις (-sis), although it could either have been formed in Greek or go back earlier. In the latter case, would be from a Proto-Indo-European *dʰéh₁tis, from *dʰeh₁- (root of τίθημι (títhēmi)). Cognates include Sanskrit अपिहिति (ápihiti), Avestan 𐬀𐬭𐬋𐬌𐬛𐬍𐬙𐬌 (arōidīti), Latin conditiō, and Gothic 𐌲𐌰𐌳𐌴𐌸𐍃 (gadēþs). More at deed.
