definition of adjectives

The adjectives are easily arranged in an order according to the mnemonic OpSiShACOM — for Opinion, Size, Shape, Age, Colour, Origin, and Material. Thus it is tired old man, where Opinion (tired) precedes Age (old) — not old tired man; and clear blue sky, where Opinion (clear) precedes Colour (blue) — not blue clear sky.
