Narrative:
We were operating on runway 33 this day. Tower requested a left turn departure for air carrier X because a flight of two military jets were ready for departure right behind them. I told tower to turn air carrier X left on a 210 heading. Tower held on to air carrier X for a couple minutes on departure climb while the flight of two military jets departed behind them on runway heading. Shortly thereafter; air carrier X came over to departure climbing out of 034 above the MVA for that area I told them to proceed direct hanaa. [I] then told the following military jet flight to turn left direct laggs. I performed coordination for the handoff of the military jet flights to boston center then switched them. My trainer alerted me that air carrier X appeared to be off course. I immediately told air carrier X to turn left direct hanaa. This appeared to do nothing; so my trainer keyed up and said turn left heading 220 and called traffic because air carrier X was now a direct conflict with the pair of military jets at their 12 to 1 o'clock around 3 to 4 miles and decreasing rapidly within a few hundred feet of each other. Air carrier X was issued a safety alert and reported the traffic in sight and was told to maintain visual separation. I'm not sure if the pilots of air carrier X saw both military jets or just one. The second military jet did not have it's transponder on so it was hard to tell how much of a factor there was between air carrier X and the second military jet. It is my understanding that air carrier X was in direct conflict because when I told them to proceed direct hanaa; they accidentally put in hanna. I've been told that this happened before. I believe that a name change should be initiated for this fix or a removal altogether to avoid future mistakes.

Title: A loss of separation event occurred when pronunciation of navigational fix HANAA was apparently incorrectly entered in the FMS as HANNA by the flight crew and an unexpected turn was initiated.
