This letter riddle asks: What appears twice in “week,” once in “year,” and never in “month”?
The answer is the letter E.
The word week contains two E’s. The word year contains one E. The word month contains no E at all.
The trick is to ignore the meaning of the words and focus only on their spelling. Because the clue mentions week, year, and month, it is easy to start thinking about calendars or time. But the answer has nothing to do with dates.
Once you look at the letters themselves, the pattern becomes clear: WEEK has two E’s, YEAR has one, and MONTH has none.
