🔼The name Aridai in the Bible
The name Aridai occurs only once in the Bible. He was one of the ten sons of Haman, who lived in Persia's winter capital Susa, and who were killed by the Jews after Haman's holocaustic intentions were foiled (Esther 9:9).
🔼Etymology and meaning of the name Aridai
The name Aridai is probably Persian and shouldn't be expected to mean anything in Hebrew. BDB Theological Dictionary suggests that our name may "perhaps" be a transliteration of the known Persian name Haridayas, which means Delight Of Hari, but also declares the text "very uncertain". Alfred Jones (Dictionary of Old Testament Proper Names) suggests our name to mean Magnus, Preaclarus (Great, Excellent), but also forwards a possible relationship with the Persian name Airyadao, meaning Digna, Dans (Worthy, Giving) or even Aryaday, which means Donum Ariae (Gift Of Arie, no really...)
A Hebrew audience, on the other hand, might have linked the name Aridai to a cluster of names that modern scholars find difficult to explain, and which may have to do with the root ערד (allowing the letter א to alternate with the ע, which sometimes happens):
The letter י (yod) upon which our name ends could be construed as the mark of an adjective, and the name Aridai could be reckoned to mean Freely. The final yod is also used to create a possessive form, which would give Aridai the meaning of My Freedom.
The final י (yod) could also be explained to come from the substantive די (day), meaning sufficient or enough (justifiably assuming that ארד plus די would assimilate into ארדי):
Hence the name Aridai also means Free Enough or Sufficiently Free.
