قسط

From the root ق س ط (q s ṭ). If the noun goes so far as to mean justice, it is perhaps a semantic loan from Classical Syriac ܩܘܼܫܬܿܵܐ (qūštā, “truth, rectitude, justice”), while others go even so far as to consider a borrowing from Latin iūstitia, whereas the use for a measure is Aramaic קִיסְטָא / ܩܸܣܛܵܐ (qesṭā) from Byzantine Greek ξέστης (xéstēs) from Latin sextārius (“a cubic measure”). The presence of a denominal verb from قِسْطَاس (qisṭās, “weigher”) is also possible.
