A fully grown female animal of a domesticated breed of ox, used as a source of milk or beef.
The top part shows two "Y" handshapes between the curved line which represents the forehead. Two dots indicate a location of where the hands touch. The digit what looks like a quotation mark means two movements of the hands. The bottom line depicts a front face with the 'oo' mouth morpheme and the fingerspelled word "moo" moving forward (the bottom line with an end dot).
