尻餅

1. Origins, structure, and basic meaning

• Structure: 尻餅 is read as しりもち and is a noun for a fall in which someone lands on their backside.
• Basic usage: Slipping appears in 滑って尻餅をつく, while falling backward appears in 後ろへ倒れて尻餅をつく.

2. Common pitfalls and similar expressions

• Fixed combination with つく
  • The usual expression is 尻餅をつく; despite the character 餅, it does not refer to eating rice cake.
• Difference from 転ぶ
  • 転ぶ broadly means to fall regardless of direction or landing point; 尻餅 specifically means landing on one’s backside.
