Aircraft X was issued Line Up and Wait (LUAW) instruction for Runway 12R. Aircraft Y had been taxied to Runway 22. I had multiple aircraft. A previous departure had not turned as instructed; so I had to coordinate a point out with departure control. I had another arrival inbound for Runway 12R. That aircraft requested to change arrival to Runway 17. After completing coordination with departure control; I mistakenly used the wrong call sign for the aircraft already in position on Runway 12R. I cleared Aircraft Y for takeoff on Runway 12R when I should have cleared Aircraft X. Aircraft Y started departure roll on Runway 22. I noticed the aircraft on Runway 12R had not started departure roll because the arrival to Runway 17 was about to turn final. Aircraft Y must have noticed the mistake and aborted takeoff on Runway 22. Aircraft X was recleared for takeoff on Runway 12R and the arrival to Runway 17 landed without further incident.  Aircraft Y taxied back to Runway 22 and departed.I accept full responsibly for this error. I am disappointed that I did not catch the call sign error. I am glad that Aircraft Y stopped. I failed in this situation. I can only try to avoid this situation in the future
An aircraft was cleared for takeoff with an arrival on short final for an intersecting runway. The departure saw the arriving traffic and aborted its takeoff. The Controller meant to clear a different aircraft for takeoff from a different runway which would not have been a confliction with the arrival.
