swoon
To feel so amazed or in love you almost faint.
To swoon means to feel suddenly weak or dizzy, sometimes fainting from overwhelming emotion, excitement, or physical distress. In older times, people would swoon from shock, extreme heat, or tight clothing, actually losing consciousness and collapsing. Today, we mostly use the word playfully to describe being overwhelmed by admiration or delight.
When fans swoon over their favorite singer, they're so excited they might feel light-headed or weak in the knees. A character in a story might swoon at the sight of something beautiful or romantic. You might hear someone say that audiences were swooning over a performance, meaning they were completely captivated and thrilled.
The word captures that feeling of being so moved by something that it affects you physically. If your friend describes swooning over the dessert table at a party, they're exaggerating how amazing it looked. If someone describes a movie as swoon-worthy, they mean it's so romantic or wonderful it makes people feel that delicious, overwhelming sensation.
Actual fainting is serious and needs attention, but swooning as we use it today is about being delightfully overwhelmed by something wonderful.
