Etymology

The word "scarecrow" combines "scare" (an older variant of "scare," meaning to frighten) and "crow" (a bird known for damaging crops). Originally, scarecrows were literal "crow-scarers," designed to mimic humans and deter birds. Over time, the term expanded metaphorically to describe anything superficially intimidating but ultimately powerless. The logic is straightforward: the object’s purpose (scaring crows) is embedded in its name.

  3. He’s just a political scarecrow—loud but with no real authority.

  4. The children giggled at the floppy hat on the old scarecrow.
