Podcast 1 — Introduction & meaning

Narrator: Today's word is "Flaw" — noun, pronounced /flɔː/, with the stress on "flaw".

Narrator: A flaw is a defect, imperfection or weakness in something or someone.

Narrator: In plain English, a flaw is a fault — like a flaw in a diamond or a flaw in a plan.

Narrator: It probably comes from the Old Norse flaga, meaning a slab or flake, suggesting a crack.

Narrator: "A flaw in" describes a defect or weakness in something, like a plan or argument.

Narrator: It differs from fault because flaw is about imperfection, whereas fault is about blame.

Narrator: "A fatal flaw" is a sense meaning a weakness that leads to downfall, like a tragic hero's flaw.

Narrator: Quality control, literature, logic, gemmology and everyday speech all rely on the word flaw.

Narrator: So remember: a flaw is a defect, possibly from the Old Norse for a slab.
