🔼The name Ami in the Bible
The name Ami occurs only once in the Bible. According to Ezra, Ami was a family-head, descending from the servants of Solomon, whose own descendants returned from exile together with Zerubbabel (Ezra 2:57).
Nehemiah offers the same list of names but reads Amon for Ami (Nehemiah 7:59). This makes scholars believe that the names Ami and Amon are closely related, and possibly two variant spellings of the same name.
🔼Etymology and meaning of the name Ami
Scholars assume that the uncommon name אמי (Ami) is a shortened form for the much more common name אמון (Amon) perhaps a Hebrew version of the way Bill relates to William. Still, it appears to be very rare to see ון-name shortened into a י-name, and the two may not be all that related. Perhaps the name Ami reminded a Hebrew audience of the word אם ('em), meaning mother of people, from the root אמם:
The post-fixed letter י (yod) could be explained as a possessive yod, and the whole name could mean My People (comparable to the name עמי, Ammi, meaning My People).
