Narrative:

Called for release for an aircraft X departure; I heard 'released;' cleared aircraft for takeoff; approximately 6 minutes later tpa approach calls asking why I released aircraft X; I told them because they said released. They said they did not say 'released' but 'hold for release.' afterwards the developmental that was monitoring said; 'tpa said released.' I have since listened to the tape but as the tpa controller was talking with either 'released' or 'hold for release;' an aircraft was announcing his departure off of tpa so there is no way to tell what the tpa controller actually said; unfortunately. 'Released' and 'hold for release.' if said fast sounds the same. I recommend another phrase from tpa to say if they cannot release an aircraft like:1) Standby2) I'll call you back3) holdthe word 'released' should not be included in any portion of an instruction from tpa in which they cannot allow that aircraft to depart.
