Narrative:

After run-up, in the run-up area at the end of runway 7 at orl, we advised ground we were ready for the takeoff. Ground said to monitor tower. We did switch to tower frequency immediately. After waiting 5-10 mins, I think I heard the tower's instructions to 'line up runway 7.' I looked at my instructor, he said 'go ahead.' we then taxied just over the hold short line. As we did a plane was landing maybe 100 ft down the runway to our left. I asked my instructor, 'are we supposed to cross the hold short line?' he said 'yes, they are very busy today and is anticipating his rollout.' we proceeded onto the runway and were cleared for takeoff. After returning to orl at XA30 local time, the tower called my flight school to talk to my instructor. My instructor just left for the day, so I called the tower. They told me what I did wrong, but said that it was ok and to be more careful. I was not familiar with the term 'line up,' if that's what I heard, my instructor may not have been familiar with that term either. I didn't hear 'hold short runway 7.' I am receiving my far/aim book to look for that term, and must be more familiar with radio phraseologies.

Narrative: AFTER RUN-UP, IN THE RUN-UP AREA AT THE END OF RWY 7 AT ORL, WE ADVISED GND WE WERE READY FOR THE TKOF. GND SAID TO MONITOR TWR. WE DID SWITCH TO TWR FREQ IMMEDIATELY. AFTER WAITING 5-10 MINS, I THINK I HEARD THE TWR'S INSTRUCTIONS TO 'LINE UP RWY 7.' I LOOKED AT MY INSTRUCTOR, HE SAID 'GO AHEAD.' WE THEN TAXIED JUST OVER THE HOLD SHORT LINE. AS WE DID A PLANE WAS LNDG MAYBE 100 FT DOWN THE RWY TO OUR L. I ASKED MY INSTRUCTOR, 'ARE WE SUPPOSED TO CROSS THE HOLD SHORT LINE?'

I WAS NOT FAMILIAR WITH THE TERM 'LINE UP,' IF THAT'S WHAT I HEARD, MY INSTRUCTOR MAY NOT HAVE BEEN FAMILIAR WITH THAT TERM EITHER. I DIDN'T HEAR 'HOLD SHORT RWY 7.' I AM RECEIVING MY FAR/AIM BOOK TO LOOK FOR THAT TERM, AND MUST BE MORE FAMILIAR WITH RADIO PHRASEOLOGIES.
