The whole matter of language is an issue with Stargate. Everybody understands each other, no matter where they from. Must be the gate or something in the water. ;-)

Hey, somebody should come up with a story that explains how and why the one or other contraction slipped into Teyla's speech in the later seasons.

Who messed with the translation programm of the gate? Who played with program of the translation nanites? *ggg*
