Natalie Portman has named her baby Aleph!
So while we have never heard this particular baby name before, we were happy to find that People.com has shared some of the name's meaning:
Aleph is the first letter of the Hebrew alphabet. Aleph is also the number 1 in Hebrew and can also be spelled "alef."
Its esoteric meaning in Judaic Kabbalah, as denoted in the theological treaty Sefer-ha-Bahir, relates to the origin of the universe, the "primordial one that contains all numbers."
We give Natalie points for picking an original baby name, and we are sure little Aleph is going to always be number one in his parent's eyes!
