the.com/elbow joint
The hinge that lets you hug, throw, and text with equal betrayal potential.
means The joint where the upper arm bone meets the two forearm bones, letting the arm bend and partly rotate.
from 'Elbow' comes from Old English 'elboga', itself a fusion of 'eln' (the forearm, related to the measurement 'ell') and 'boga' (a bow or bend — the same root as 'bow' in archery). So the word literally means 'arm-bend,' a plain, practical compound built long before anyone needed it for texting.
