Narrative:
We were near kikkr on the gibbz 2 arrival and cleared direct mosby. We misheard the clearance and proceeded to mosle. Shortly after; the controller asked if we were still on the arrival and we said yes. He said no problem that happens here and he meant for us to proceed to mosby on the approach to runway 1R; he then gave us a vector. Either mosle or mosby needs to be renamed they are too similar in spelling and sound.
