A ~ A bit much A picture is worth a thousand words A rolling stone gathers no moss A steal Abide by a decision About face Above board Accident waiting to happen Ace up your sleeve Achilles' heel Acid test Across the board Actions speak louder than words Add fuel to the fire Add insult to injury After your own heart Against the clock Against the grain Ahead of the pack Ahead of time All along All hell broke loose All over the place All over the shop All set All square Alter ego Ambulance chaser Argue the toss Arm and a leg Armchair critic As a rule As the crow flies Asleep at the wheel At a loose end At arm's length At cross purposes;.;At each other's throats At loggerheads At odds At sea At the drop of a hat At the end of the day At the end of your tether At your wits' end Axe to grind
