Here is a quick riddle to test your thinking: What has a thousand letters but never writes a word? The clue is the word “letters,” which can mean more than one thing.
Think of Letters as Mail
When you read the riddle, you might imagine alphabet letters on a page. But the answer doesn’t have to involve spelling, books or writing at all.
A letter can also be something written, placed in an envelope and sent through the mail. Once you switch to that meaning, the possibilities become clearer.
The Riddle Answer
The answer is a post office. A post office can hold, sort and process thousands of mailed letters without writing a single word itself.
The trick is that a post office possesses letters in the mail sense, not in the sense of being an author. A mailbox is another answer people sometimes suggest, but “post office” fits the idea of handling a large number of letters particularly well.
Why Wordplay Riddles Work
Good riddles encourage you to abandon the most obvious interpretation of a familiar word. Once you recognize the double meaning, the answer suddenly seems simple.
Did you guess post office before reading the explanation, or did you think of something else?
