The term 'clutch tightly' can be expressed in three different ways: GRASP (5 letters), GRIP (4 letters), and holdon (6 letters). Grasping is the act of taking something firmly with the hand, while gripping is a stronger form of grasping. Holdon is an even stronger form of grasping, as it implies that one is holding on to something with great strength. All three words describe the action of clutching something tightly.
