What come once in a moment, twice in a minute and never in a thousand years?

the letter m

oops. better pick a different letter.

I read it backwards.

The riddle should probably be once in a minute and twice in a moment . . .

The answer to the riddle "What comes once in a moment, twice in a minute, and never in a thousand years?" is the letter "M."

To understand the answer, let's break it down:

1. "What comes once in a moment": In this context, "moment" refers to a very short period of time, typically understood as a brief instant. The letter "M" appears only once in the word "moment."

2. "Twice in a minute": This refers to the word "minute," meaning 60 seconds. The letter "M" appears twice in the word "minute."

3. "Never in a thousand years": In this case, "thousand years" is used to signify an extremely long period of time. The letter "M" doesn't appear in the phrase "thousand years" at all.

So, the letter "M" fits the criteria given in the riddle, as it appears once in "moment," twice in "minute," but never in "thousand years."
