Mandarin, a Chinese language spoken on Earth. Dr. Lindsay said that she was fluent in this language, when applying for a post at SG-1, when Lt. Colonel 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 Dr. 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 International Oversight Advisory Representatives to the Gamma Site. (SG1: "The Scourge")
Behind the scenes[]
- In the comments of the DVD it is said that Mitchell cannot speak Mandarin. He only knows this one word so he can say it whenever someone is talking about him in Mandarin. It means "screw you".
