Narrative:
On a approach to runway 30 at mia we were given a turn to 70 degree, a modified base leg. As we descended from 7000 ft to 3000 ft, ATC then asked if we had a foreign carrier in sight and the airport. We had the airport. They stated the other carrier was crossing the 'shoreline.' we spotted an aircraft crossing the shoreline of the harbor so called traffic in sight. We were cleared for a visual approach to 30. A min later approach called traffic 12 O'clock on an intercepting flight path. We were cleared to overshoot the final approach path and 'south' turn behind the large transport on the visual to 30. Confusion resulted from the term 'shoreline.' the controller apparently meant the ocean shoreline. We all looked to the harbor shoreline. Since we saw traffic over the harbor we called traffic in sight. If the controller had called an 'O'clock' and ocean shoreline or DME a potential conflict may have been avoided. We avoided all conflicts and landed without incident.

Title: POTENTIAL CONFLICT OCCURS WHEN ACR LGT FLC PICK OUT WRONG ACFT TO FOLLOW FOR A VISUAL APCH.
Narrative: ON A APCH TO RWY 30 AT MIA WE WERE GIVEN A TURN TO 70 DEG, A MODIFIED BASE LEG. AS WE DSNDED FROM 7000 FT TO 3000 FT, ATC THEN ASKED IF WE HAD A FOREIGN CARRIER IN SIGHT AND THE ARPT. WE HAD THE ARPT. THEY STATED THE OTHER CARRIER WAS XING THE 'SHORELINE.' WE SPOTTED AN ACFT XING THE SHORELINE OF THE HARBOR SO CALLED TFC IN SIGHT. WE WERE CLRED FOR A VISUAL APCH TO 30. A MIN LATER APCH CALLED TFC 12 O'CLOCK ON AN INTERCEPTING FLT PATH. WE WERE CLRED TO OVERSHOOT THE FINAL APCH PATH AND 'S' TURN BEHIND THE LGT ON THE VISUAL TO 30. CONFUSION RESULTED FROM THE TERM 'SHORELINE.' THE CTLR APPARENTLY MEANT THE OCEAN SHORELINE. WE ALL LOOKED TO THE HARBOR SHORELINE. SINCE WE SAW TFC OVER THE HARBOR WE CALLED TFC IN SIGHT. IF THE CTLR HAD CALLED AN 'O'CLOCK' AND OCEAN SHORELINE OR DME A POTENTIAL CONFLICT MAY HAVE BEEN AVOIDED. WE AVOIDED ALL CONFLICTS AND LANDED WITHOUT INCIDENT.
