The Once in a Minute Riddle

I show up once in a minute,
twice in a moment,
but never in a thousand years.
What am I?
💡 Hint

Stop thinking about time. Start thinking about spelling.

Reveal answer

The letter M.

Spell it out. “Minute” contains one M. “Moment” contains two M’s. “A thousand years” contains no M at all. The riddle disguises a spelling question as a question about time, so your brain looks for an event or object instead of a letter. Once you read the clues as words rather than ideas, the answer is easy to check.

Did you know?Letter riddles are a favorite of puzzle makers because they hide in plain sight. The same trick appears in many forms: what is at the end of a rainbow (the letter W), what is in the middle of Paris (the letter R). When a riddle stacks up oddly specific words, it is worth checking their spelling before anything else.

About This Puzzle

This one is labeled hard for a reason. Most people start thinking about clocks, time and history, and that is exactly where the riddle wants you to go. Try not to fall for it.

How to Think About It

The riddle is packed with time words: minute, moment, thousand years. That is the misdirection. Instead of thinking about how long things last, look at the words as written on the page. What could appear once in one word, twice in another, and zero times in a longer phrase?
