Other forms: salvers
A salver is a fancy serving tray that's usually made of silver. If the Queen of England is dropping by for lunch, you might want to set the table with your best salvers!
While salvers are sometimes made of another metal (or even glass), they're mainly silver trays used in special circumstances. Years ago, servants would serve food using a salver, or collect glasses and carry them away on a salver. If you were a wealthy person sitting at your writing desk, a maid or butler might even have brought your mail on a salver. The word comes from the French salve, "tray for presenting objects to the king."
