1. See catch. 10. Grasp, reach refer to the power of seizing, either concretely or figuratively. Grasp suggests actually seizing and closing the hand upon something (or, figuratively, thoroughly comprehending something) and therefore refers to what is within one's possession or immediate possibility of possession: a good grasp of a problem; immense mental grasp. Reach suggests a stretching out of (usually) the hand to touch, strike, or, if possible, seize something; it therefore refers to a potentiality of possession that requires an effort. Figuratively, it implies perhaps a faint conception of something still too far beyond one to be definitely and clearly understood.
