Why this word is great
KILIG — [Adjective] A giddy, fluttery excitement, especially from romantic tension or anticipation. Borrowed from Tagalog kilig, with no further known etymology. Unlike "excitement" (a broad surge of energy) or "infatuation" (a sustained, consuming crush), kilig is the fleeting, fizzy high of a first touch, a whispered compliment, or a glance held a second too long. It is the involuntary smile when your phone lights up with their name, the way your pulse jumps at the sound of their voice, the electric warmth of a hand brushing yours in a crowded room—proof that the body, too, has its own fragile, wordless language.
