In Egyptian mythology, Huh (also spelled Hu, Hah, or Heh) was the deification of eternity in the Ogdoad, his name itself meaning endlessness, and is not to be confused with the identically named Hu a god in the Ennead system. As a concept, he was androgynous, his female form being known as Hauhet, which is simply the feminine form of his name.

Huh is a simple sound representing confusion of the one making it, similar to "er" or "uh" and other speech disfluencies. Huh is pronounced with a nasal vowel at the end. It can also represent unarticulated muttering such as in Huh-euh-huh.
