The word “toast”, meaning a wish of good health, started in ancient Rome, where a piece of toasted bread was dropped into wine.
(To toast – to make bread or other food warm, crisp and brown by putting it near a high heat.
To toast – to hold up your glass and then drink as an expression of good wishes or respect.
At weddings in the UK people toast the bride and groom. Luckily it is the second meaning not the first.)
