masc voc pl of hu (noun)
Etymology. From the root √hu (to call, invoke, sacrifice), cognate with Sanskrit hu- and Greek ὕω (hýō, to sacrifice). The particle 'truly, indeed' is an exclamatory usage derived from the imperative or vocative force of ritual invocation. The agent noun 'killer' develops from the root's sense of 'striking' or 'dealing a blow' in sacrifice.
