A three-letter word I'm sure you know, I can be on a boat or a sleigh in the snow, I'm pals with the rain and honor a king, But my favorite use is attached to a string. What am I?

Why this works

This riddle cleverly plays with the different meanings of the word "bow." First, "bow" refers to the front of a boat, which is a common term in nautical contexts. Then, it mentions being "on a sleigh in the snow," which could refer to a decorative bow often used during winter or festive seasons. The line about being "pals with the rain" hints at the bow being part of a rainbow, while "honor a king" alludes to the act of bowing as a sign of respect. Finally, the favorite use "attached to a string" directly points to a bow used in archery or as a decorative element, tying all these meanings together in a fun and engaging way!
