Stumped by this crossword clue? Prepare to be amazed!

The crossword question “Wow, that’s upside down!” is a cryptic clue that indicates the answer is a word that can be read the same way when turned upside down. In this case, the answer is “MOM” because when the word “MOM” is flipped, it still remains as “MOM.” This clue is a playful way to hint at the palindrome nature of the word “MOM,” where it reads the same whether it is read left to right or right to left.
