While taxiing southeast our left wing tip apparently struck the elevator of the aircraft [on the adjacent taxiway]. We taxied back to the gate. No reported injuries to passengers or crew.
During taxiing; we were transitioning from taxiway A to taxiway B via intersection A6. As we approached intersection A7; there was an Air Carrier Y aircraft attempting to transition to taxiway A via A7. We maneuvered to the right to avoid Air Carrier Y and attempt to reposition back on center line of taxiway B. At that point I felt a shudder of our aircraft and we stopped. I told ground that we needed to stop on the taxiway to figure out what caused the shudder. We were then told by an aircraft behind us that our left wing tip and the empennage of the Air Carrier Y plane at A7 had clipped one another. Cause: Lack of training stressing the importance of how much bigger the wingtip is when taxiing when taxiing an A321 aircraft.
A321 flight crew reported their wingtip made contact with another aircraft's empennage during taxi.
