Two rehearsals for his prime-time speech were not enough to keep U.S. President George W. Bush from mangling the name of the Abu Ghraib prison that brought shame to the U.S. mission in Iraq.

During the half-hour televised address, Bush mispronounced Abu Ghraib each of the three times he mentioned it while announcing U.S. plans to tear down the infamous jail and replace it with a new facility.

The prison, the scene of torture under Saddam Hussein and the setting for the Iraqi prison abuse scandal under the U.S. military, has a name that English speakers usually pronounce as "abu-grabe".

But the Republican president, long known for verbal and grammatical lapses, stumbled on the first try, calling it "abugah-rayp". The second version came out "abu-garon", the third attempt sounded like "abu-garah".

White House aides, who described the speech as an important address on the future of Iraq, said Bush practised twice on Monday before boarding his helicopter for his trip to the speaking venue at the U.S. Army War College in Carlisle, Pennsylvania.
