Fraenkel 1893, 80, claims that Syr. gwstbryn, and its dialectal variant psṭrʾ (attested in the ancient dialect of Tikrit), are words of Persian origin, and correspond to NP kaštara a carpenter's axe (Steingass 1032); Fraenkel argues that the model of the Syriac loanwords was an antecedent of NP kaštara, namely OIr. *bistara- (*wistara-), whose etymon Fraenkel does not try to explain further ● psṭrʾ EN 30, 67; BB 1586, 22; gwstbryn BB 471, 8 ◆ LS 127a; 581a–b: Pers.; Duval index pers. 223 and 225
