🔼The name Anaiah in the Bible
The name Anaiah occurs twice in the Bible, both times in the book of Nehemiah, and so these two Anaiahs may very well be the same one. He's mentioned first among the seven chief explainers who assisted Ezra the reformer in conveying the Law to the people (Nehemiah 8:4). Anaiah is also listed among the signers of the new covenant (Nehemiah 10:22).
🔼Etymology of the name Anaiah
The name Anaiah consists of two elements. The first part of the name comes from the enormous root group ענה ('ana):
The second part of the name Anaiah is the appellative יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton יהוה, YHWH, or Yahweh.
For a meaning of the name Anaiah, NOBSE Study Bible Name List reads Yahweh Has Answered. Jones' Dictionary of Old Testament Proper Names has Answer Of The Lord. BDB Theological Dictionary does not translate.
Note that the form עניה occurs three other times, as feminized versions of the adjective אני ('ani), meaning wretched or poor (Isaiah 10:30), or afflicted (Isaiah 51:21 and 54:11). Our name could very well also be interpreted as such, or even as Afflicted Of Yah, as an obvious paraphrasing of Isaiah's famous Messianic statement מכה אלהים ומענה (Isaiah 53:4); the final word being of the same root as our word אני ('ani).
