Etymology
Origin of jamb
1350–1400; Middle English jambe < Middle French: leg, jamb < Late Latin gamba, variant of camba pastern, leg < Greek kampḗ bend of a limb
Explanation
A jamb is one of the upright boards or posts that support a door or window frame. Your front door shuts securely in between two jambs. When a house builder frames a doorway, she sets two jambs at the sides of the opening, with what's called a lintel at the top. The door fits between the jambs. Windows have jambs too — if you replace your existing windows, you may need a whole new frame, including new jambs. The Old French origin is jambe, which means "pier or side post," but was originally "a leg or a shank," from the Late Latin gamba, "leg."
