Connected with Old Armenian հաստ (hast, “firm, steady, standing still, tough; thick, dense, broad”), possibly also Sanskrit पस्त्य n (pastyá, “stall, stable ← stable habitation”), पस्त्या f (pastyā́, “homestead, dwelling, household”), and usually derived from Proto-Indo-European *pastV- (“solid, stable”). Kroonen separates the Sanskrit and reconstructs the Proto-Indo-European root for Armenian and Germanic as *pHst-, according to him from earlier *ph₂ǵ-sth₂-, a compound of *peh₂ǵ- (“to become firm”) (compare Ancient Greek πήγνυμι (pḗgnumi, “to fasten, fix, make solid”)) and *steh₂- (“to stand”).
However, according to Martirosyan “we are hardly dealing with a Proto-Indo-European word,” rather a substrate word shared by Armenian, Germanic, and possibly also Indo-Aryan. See հաստ (hast) for more on this.
