א Aleph is the first letter of the Kabbalistic alphabet, or better said, the Kabbalistic Aleph-bet. Aleph is also the first letter in the Arabic alphabet, but it is pronounced Alif.
With this letter we write many names, such as אלוהים Elohim, which is precisely the Hebrew word for Gods and Goddesses.
