weak, debilitated, decrepit, feeble, frail, infirm
Someone who is weak lacks physical, mental, or moral strength (a weak heart; a weak excuse; too weak to resist temptation). But there's nothing to suggest what the cause of this lack of strength might be. Someone who is frail, on the other hand, is weak because he or she has a slight build or delicate constitution (a small, frail man). Calling someone feeble implies that his or her weakness is pitiable (too feeble to get out of bed); when applied to things, feeble means faint or inadequate (a feeble light). Infirm suggests a loss of soundness, as from aging or illness (poverty and illness had made him infirm). Debilitated and decrepit also suggest that strength once present has been lost. But while someone who is young may be debilitated by disease, decrepit specifically refers to a loss of strength due to advanced age or long use (a decrepit old woman who seldom left her house; a decrepit building that would soon be torn down).
