voilà

There it is; there you are. An exclamation calling attention to or expressing satisfaction with something that has just been presented or accomplished. Taken from the French for "look there," though often spelled without the accent mark in English. (Pronounced "vwalla," with emphasis on the second syllable.) Finally, you just turn this crank to set it into place and—voila! The machine is ready to go. "Voilà!" said the magician as he pulled the girl's card from his pocket.
