What it means
Having a glow is radiating health, happiness or confidence so visibly that people notice you are shining from the inside out. Often the glow of someone in love or really thriving.
Usage examples
"You have such a glow today, what is your secret?"
"Ever since the holiday she has had this glow."
"Nah, babe, you're glowing lately. New job, new crush, or are you just finally sleeping properly?"
"He walked in with that proper glow, like life's been treating him sweet for once."
Where it comes from
It’s straight from the ordinary English word glow, meaning a soft, steady light. From there it slid naturally into describing people who look visibly radiant, healthy, happy, in love, or just in a really good place. That figurative use has been around in everyday English for ages.
