means The broken-down, worn-out state a person or thing falls into after long age, neglect, or hard use.

from From Latin decrepitus, 'very old, broken down,' built from the intensive prefix de- plus crepare, 'to crack, creak, or rattle' — the same root that gives English 'crepitation' (the crackling sound of old joints). So decrepitude is literally a thing that has cracked and creaked its way through time; the word itself sounds like the hinges it describes.
