The Goa'uld language has numerous similarities with Unas, leading some to believe that the former was derived from the latter. Whether or not this is true, there are some similarities, not least of which is the subject-verb-object word order. There are also vocabulary similarities, as follows:
- KEKA/Khek: "Kill" or "death" in both Goa'uld and Unas.
- ONAC: In Goa'uld, "onac" means "sentient being". In Unas, it means "Goa'uld".
- TOK: In Unas "tok" means "against" while the Tok'ra are the Goa'uld against Ra.
