Mandarin
From SGCommand
Mandarin, a Chinese language spoken on Earth. An Air Force Linguist said that she was fluent in this language, when applying for a post at SG-1, when Cameron Mitchell assumed command over the unit. (SG1: "Avalon, Part 1") However, Mitchell may not have been impressed as he himself spoke and understood the language with at least some proficiency - a fact which surprised Daniel Jackson and Shen Xiaoyi after they believed they had shared a private joke at Mitchell’s expense in the Embarkation room prior to the visit by IOA representatives to the Gamma Site. (SG1: "The Scourge")
