The word "抱抱" is formed through the simple, expressive act of doubling the single character 抱 (bào), which means "to hug" or "to embrace". This repetition mimics the action itself, suggesting not just a single hug, but a sustained, affectionate, or comforting embrace, often conveying a sense of warmth, care, or a desire for reassurance. It transforms a basic action into something more tender, intimate, and often childlike or soothing, creating its meaning directly through the rhythmic, physical echo of the character.
