The word "搓揉" is formed by combining the characters "搓" and "揉", both containing the hand radical "扌" to indicate manual actions. "搓" means to rub or twist, while "揉" means to knead or massage; their conjunction creates a compound word that emphasizes the intertwined actions of rubbing and kneading, typically performed with the hands. This formation directly merges two semantically related characters to specify a cohesive physical activity.
