Narrative:

We landed on ord runway 9R and turned off the runway onto taxiway M5. Ord tower cleared us to our gate via a left turn onto taxiway D and via taxiway a. On taxiway A16, wbound, approaching taxiway a, I saw an MD80 on taxiway a, also wbound. The MD80 was converging and closing from behind us and from our right. I told the captain to stop immediately and backed him up by guarding my set of brakes. The captain immediately stopped our aircraft, still on taxiway A16. The MD80 continued in front of us on taxiway a with no apparent speed change. I then confirmed with ord tower that our original clearance was to taxi from taxiway M5 to the gate and remain on tower frequency. Ord tower responded that this was true and added that the MD80 was on ord ground frequency and that the ord ground controller apologized for the incident.
