Side-by-side comparison

Trick to remember it

'Wail' without H — short, immediate, like a sharp cry. 'Whale' with silent H and LE — bigger, longer word like the whale itself.

Quick rule

Is it the cry of pain or grief? 'Wail'. Is it the marine mammal? 'Whale'.

Did you know?

The blue whale is the largest animal in Earth's history — larger than any dinosaur that ever lived. Its heart weighs as much as a small car, and its call is the loudest of any animal, audible up to 800 km away. 'The Wailing Wall' in Jerusalem (also called the Western Wall) gets its English name from centuries of Jewish mourners wailing prayers for the destroyed Temple. 'Whale' comes from Old English 'hwael' — related to German 'Wal'. Some whales were hunted almost to extinction; the blue whale population dropped by 99% during commercial whaling in the 20th century.
