Narrative:
I was working ground; clearance; and controller in charge. I had just taxied an air carrier out to xyl. A B737 was taxiing behind the first aircraft on taxiway foxtrot. I had passed the strip to local control. I then overheard local talking to the B737 about an E4 departure because they wanted to go in front of the first aircraft because they were taxiing to slow. I heard local give the distance remaining and then cleared the B737 for takeoff on xyl at echo 4. In the meantime I had a couple more aircraft taxiing out to xyl on delta to foxtrot. I heard local again tell the B737 crew no delay because traffic was on final getting closer. After hearing this I started watching B737; they made the right turn down taxiway echo and passed E4 and picked up speed. I told local what I was seeing; as they were watching as well. Before the B737 could pick up any more speed or do anything else. Local control told them to stop repeatedly. They then told B737 they were on a taxiway and to turn back on foxtrot for the full length take off. B737 crew told local they thought they were north of E4 so they were taxiing down echo to the E4 intersection.no recommendations at this time. Everything was handled and caught before anything could happen.
