Narrative:

The captain started to taxi and talk to ground control. After getting taxi clearance, the captain gave me the controls not telling the exact clearance. I taxied to runway 16 at gcc. We crossed runway 21 on our way to runway 16. Finding out from ground control that we were to taxi to runway 21, not runway 16. We asked ground control about the wind. It was alright to continue to runway 16 which we did. The captain and I should have clarified the clearance when he gave me the controls. I had never taken off from runway 21. The main runway is 16-34 so I assumed runway 16.
