• As afraid as a grasshopper
• As active as quicksilver
• As ageless as the sun
• As agile as a cat
• As agile as a monkey
• As alert as a bird
• As alike as two peas in a pod
• As alone as Crusoe
• As ambitious as the devil
• As ambitious as Lady Macbeth
• As ancient as the sun
• As ancient as the stars
• As angry as a wasp
• As arid as the sand of Sahara
• As artificial as the clockwork
• As artificial as made-ice
• As awful as justice
• As awful as thunder
• As awful as silence
• As awkward as a cow on ice
• As mad as a hatter
