Podcast 1 — Introduction & meaning

Narrator: Today's word is "Quash" — verb, pronounced /kwɒʃ/, with the stress on "quash".

Narrator: To quash is to reject, suppress or overturn, especially a legal decision or a rebellion.

Narrator: In plain English, to quash is to crush something — like a court quashing a conviction or a government quashing a revolt.

Narrator: It comes from the Old French quasser, meaning to annul or crush, from the Latin cassare, meaning to nullify or set aside.

Narrator: "To quash a conviction" describes a court overturning a guilty verdict so it no longer stands.

Narrator: It differs from squash because quash is a legal or formal term for overturning, whereas squash means to physically crush flat.

Narrator: "To quash a rebellion" is a sense meaning to put down an uprising by force.

Narrator: Law, politics, military and governance all rely on the word quash.

Narrator: So remember: to quash is to overturn or suppress, from the Old French for to annul.

Podcast 2 — In conversation

Speaker A: Is quash the same as squash?

Speaker B: Related but more formal! QUASH comes from the Old French quasser, meaning to annul, so it's about rejecting or overturning, especially in law, not just crushing flat.

Speaker A: So a court can quash a verdict?

Speaker B: Exactly — that's its main legal use!

Speaker A: Example sentences?

Speaker B: "The court quashed the conviction"; "police quashed the riot"; "she quashed the rumour" — a verdict, a revolt and a story.

Speaker A: Common mistakes?

Speaker B: Don't use quash for physically crushing something soft, because quash is for overturning or suppressing, while squash is for flattening.

Speaker A: Close relatives?

Speaker B: "Overturn" the legal cousin, "suppress" the forceful twin, "annul" the formal alternative. The word keeps its decisive charm!
