The engineer explained how the crosshead connects the piston rod to the connecting rod in the engine.
Crosshead is formed from "cross" (from Old English "cros", meaning a structure or figure resembling a cross) and "head" (from Old English "heafod", meaning the top or upper part). The term refers to a part of a machine or structure that is shaped like a cross and is located at the top or head of something.
Think of a 'cross' shape at the 'head' or top of a structure — that's what a crosshead is.
