Nobody knows for sure where the term ‘Indian Summer’ comes from.

The word ‘hippocampus’ refers to three different things:

• the sea-horses that drove Poseidon’s chariot
• seahorses, the fish
• the part of the brain that kind of looks a lot like a seahorse

The hyphen distinguishes between the mythological creature and the fish.

In Agatha Christie’s Murder At the Vicarage the term ‘shemozzle’ appears in the following dialogue:

“I expect you’d find her in the studio in the garden — sitting to Lawrence Redding.”
“There’s been quite a shemozzle about him,” said Lettice. “With father, you know. Father’s dreadful.”

‘Shemozzle’ is borrowed from the Yiddish ‘shlimozel,’ usually meaning ‘misfortune.’
