Narrative:

Contacted ground at K1. Ground controller asked if we wanted runway 9R or runway 14R based on the winds. Requested runway 14R. Controller told us to taxi via txwys K, T11, and T to runway 14R, cleared to cross runway 9R/27L. After crossing runway 14R/32L, the captain and I realized the ground controller did not state 'cleared to cross runway 14R/32L.' no conflict. Believed the instructions implied that we were cleared to cross all runways to runway 14R. In the future, I will make sure what the controller's intentions are by asking him to clarify. If there is any doubt, ask! Supplemental information from acn 600752: I think the controller gave incomplete and misleading instructions.

Narrative: CONTACTED GND AT K1. GND CTLR ASKED IF WE WANTED RWY 9R OR RWY 14R BASED ON THE WINDS. REQUESTED RWY 14R. CTLR TOLD US TO TAXI VIA TXWYS K, T11, AND T TO RWY 14R, CLRED TO CROSS RWY 9R/27L. AFTER XING RWY 14R/32L, THE CAPT AND I REALIZED THE GND CTLR DID NOT STATE 'CLRED TO CROSS RWY 14R/32L.' NO CONFLICT. BELIEVED THE INSTRUCTIONS IMPLIED THAT WE WERE CLRED TO CROSS ALL RWYS TO RWY 14R. IN THE FUTURE, I WILL MAKE SURE WHAT THE CTLR'S INTENTIONS ARE BY ASKING HIM TO CLARIFY.
