Podcast 1 — Introduction & meaning

Narrator: Today's word is "Radiant" — adjective, pronounced /ˈreɪdiənt/, with the stress on "ra".

Narrator: Radiant means shining brightly, or showing great joy or health.

Narrator: In plain English, radiant describes someone glowing with happiness or a light shining brightly.

Narrator: It comes from the Latin radians, meaning shining, from radiare meaning to beam or shine, from radius meaning a ray.

Narrator: "A radiant smile" describes a beaming, joyful expression that lights up a face.

Narrator: It differs from bright because radiant implies warmth and joy, whereas bright just means giving off light.

Narrator: "Radiant heat" is a technical sense meaning heat that travels as infrared rays, warming objects directly.

Narrator: Beauty, health, physics, heating and everyday description all rely on the word radiant.

Narrator: So remember: radiant means shining or joyful, from the Latin for shining.
