a wooden excuse to lean on, doubling as the body's most honest confession of need

means A support, originally a wooden staff fitting under the arm, used to help someone walk when a leg or foot can't bear weight — and, by extension, anything one leans on too heavily to avoid coping alone.

from From Old English 'crycc,' a staff or stick — a word with sturdy Germanic cousins like Dutch 'kruk' and German 'Krücke,' all sharing a sense of something bent or hooked. The root idea seems to be the crook of the thing, the bent top that tucks under the arm or fits the hand. The figurative 'crutch,' meaning a habit or person you depend on too much, is a much later flowering of the same image: a prop for the limping spirit rather than the limping leg.

ancient origin
Egyptians used them over 4,000 years ago
underarm myth
leaning on the armpit can damage nerves there
linguistic leap
means any emotional support you can't quit
forearm upgrade
crutches now mostly rest on wrists, not pits

lofstrand crutch — forearm crutch with curved arm piece, invented by albert lofstrand jr. in 1945, standard assistive device
