Etymology Origin:
The word "interest" originates from Latin interesse ("to be between, to concern"), combining inter- (between) and esse (to be). Initially, it referred to compensation for loss (legal/financial context), later expanding to mean "curiosity" or "stake in something." The dual meanings—financial and emotional—reflect its logical progression from tangible (money) to abstract (attention).
