🔼Etymology of the name Izri
The etymology of the name Izri can be traced to the following root cluster, and most likely to the verb יצר (yasar), meaning to fashion or form:
The letter י (yod) upon which our name ends, may either create an adjective (rocky), a possessive form (my form), or may be a remnant of 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 Izri, NOBSE Study Bible Name List reads Fashioner. Jones' Dictionary of Old Testament Proper Names deems the final yod to be the mark of a possessive form and proposes The Form Of "i.e. his parents". BDB Theological Dictionary does not translate the name Izri but does list it under the verb יצר (yasar), meaning to fashion or form.
