Narrative:

While holding short for takeoff on runway 9L; the tower indicated that we should expect an expeditious takeoff clearance (before the flight on final at approximately the FAF). They then cleared us onto hold which I repeated 'cleared onto hold; line up and wait.' I intentionally added the 'line-up and wait' because it is common international terminology only used with the into position and hold clearance; thus reaffirming what she wanted us to do. As we took the runway; we were anticipating an immediate clearance for takeoff; therefore; we did not set the parking brake once into position. However; we continued holding in position for what seemed to be approximately 1 min before the controller told us to clear the runway then quickly amended that and told us to hold our position. At that time; she appeared to be directing the aircraft on final to go around (she spoke to him in portuguese). I confirmed with her in english that; in fact; she was sending him around since we were still in position. In reviewing this situation; the communication disparity points in 2 directions: either her intention was to subsequently clear us for an immediate takeoff as we took the runway and it was never transmitted; or her clearance was to hold short which is not what we heard and 'not' what we read back.

Title: B767-300 FLT CREW ENCOUNTERS LANGUAGE BARRIER PROBS AT SBGR RESULTING IN A POSSIBLE RWY INCURSION INCIDENT.

Narrative: WHILE HOLDING SHORT FOR TKOF ON RWY 9L; THE TWR INDICATED THAT WE SHOULD EXPECT AN EXPEDITIOUS TKOF CLRNC (BEFORE THE FLT ON FINAL AT APPROX THE FAF). THEY THEN CLRED US ONTO HOLD WHICH I REPEATED 'CLRED ONTO HOLD; LINE UP AND WAIT.' I INTENTIONALLY ADDED THE 'LINE-UP AND WAIT' BECAUSE IT IS COMMON INTL TERMINOLOGY ONLY USED WITH THE INTO POS AND HOLD CLRNC; THUS REAFFIRMING WHAT SHE WANTED US TO DO. AS WE TOOK THE RWY; WE WERE ANTICIPATING AN IMMEDIATE CLRNC FOR TKOF; THEREFORE; WE DID NOT SET THE PARKING BRAKE ONCE INTO POS. HOWEVER; WE CONTINUED HOLDING IN POS FOR WHAT SEEMED TO BE APPROX 1 MIN BEFORE THE CTLR TOLD US TO CLR THE RWY THEN QUICKLY AMENDED THAT AND TOLD US TO HOLD OUR POS. AT THAT TIME; SHE APPEARED TO BE DIRECTING THE ACFT ON FINAL TO GO AROUND (SHE SPOKE TO HIM IN PORTUGUESE). I CONFIRMED WITH HER IN ENGLISH THAT; IN FACT; SHE WAS SENDING HIM AROUND SINCE WE WERE STILL IN POS. IN REVIEWING THIS SITUATION; THE COM DISPARITY POINTS IN 2 DIRECTIONS: EITHER HER INTENTION WAS TO SUBSEQUENTLY CLR US FOR AN IMMEDIATE TKOF AS WE TOOK THE RWY AND IT WAS NEVER XMITTED; OR HER CLRNC WAS TO HOLD SHORT WHICH IS NOT WHAT WE HEARD AND 'NOT' WHAT WE READ BACK.
