kvell

To "kvell" is to feel an overwhelming sense of pride and joy, typically in response to the achievements or successes of someone you love, such as a child or a close friend. The mental image is that of a beaming parent watching their kid graduate or perform on stage, their heart swelling with a warmth that is impossible to hide. It is a Yiddish-derived term that fits perfectly into informal English to describe a "proud parent" moment. While it specifically centers on the pride one takes in others, it is often used with a touch of affectionate exaggeration or self-awareness, as in "I'm kvelling over my daughter's new promotion."
