Judah is a masculine given name of Hebrew origin.
It is the English form of Yehudah (Hebrew: יְהוּדָה), the Hebrew name of the biblical figure Judah, founder of the Tribe of Judah and thus, the eponym of the Kingdom of Judah and the Jews.
The Hebrew name for Judah, Yehuda (יהודה), literally "thanksgiving" or "praise," is a variant form of the root Y-D-H (ידה), "to thank" or "to praise.
"[1] His birth is recorded at Gen. 29:35; upon his birth, Leah exclaims, "This time I will praise the LORD/YHWH," with the Hebrew word for "I will praise," odeh (אודה) sharing the same root as Yehuda.
Alternatively, Edward Lipiński connected Hebrew yĕhūdā with Arabic whd / wahda "cleft, ravine".
