Sense: noun/1
These four words describe connected parts of the upper limb, and learners often mix them up. 'Arm' is the broadest term — it covers the whole limb from shoulder to hand ('She carried the bag in her arm'). 'Forearm' is the section between the elbow and the wrist ('He rested his forearm on the table to write'). 'Wrist' is the joint that connects the forearm to the hand ('She wore a watch around her wrist'). 'Elbow' refers only to the hinge-like joint at the midpoint of the arm. A good way to remember: when you bend your arm, the elbow is the point that sticks out; what goes up is the forearm; the part above is the upper arm; and the whole thing is the arm.

Etymology
Elbow comes from Old English 'elnboga,' a compound of 'eln' (forearm, a unit of measurement) and 'boga' (bow or arch). The word literally meant 'arm bend.' Similar compounds exist across Germanic languages, such as German 'Ellenbogen' and Dutch 'elleboog.' The image of a bent arm has also shaped the word's extended uses for pipe fittings, road turns, and basketball positions.
