Narrative:
We were holding short of runway 19R. Tower gave us a clearance that we thought was to taxi in position and hold, and what he actually meant was taxi closer to the hold line and hold. His transmission was very fast and slightly garbled. I asked the first officer what was said by the tower, and he confirmed taxi in position and hold. Tower was very busy. No incident involved due to no lndgs, and an aircraft had just taken off.
