LONG (duration/length): Uses two B-hands, often with one hand stationary and the other moving over it, or both hands moving linearly. 'Extension' implies an added part or prolongation, while 'long' describes inherent length or duration. ADD: Typically uses one or two F-hands or O-hands, often bringing them together or placing one on top of the other. 'Extension' focuses on increasing length/size, 'add' is a more general concept of combining or increasing quantity. GROW: Often uses an open B-hand or 5-hand moving upwards or outwards from a starting point, sometimes with a squeezing motion. 'Extension' is about deliberate lengthening/adding, 'grow' implies natural development or increase in size
