U+2137 "ℷ" Gimel Symbol is a typographic representation of the third letter of the Hebrew alphabet, gimel, used within mathematical notation to denote specific functions or logical concepts, most notably the gimel function in set theory which describes cardinal exponentiation.

This character belongs to the Letterlike Symbols block in Unicode, serving as a semantic symbol rather than a simple alphabetic character.
