An older doublet of دَرْز (darz, “suture”). Compare Persian تراز (tarâz, “raw silk”), تراز (terâz, torâz, “beauty, adornment”), ترازیدن (tarâzidan, “to adorn, to embellish; to embroider”), with the vocalism also passed as Arabic طِرَاز (ṭirāz), and this spelling made the Persian spelling طرازیدن (tarâzidan). Note also Old Armenian տարազ (taraz), a Middle Iranian borrowing.
