Morphology

lockjaw = lock + jaw (semi-transparent) = lock + jaw

The components 'lock' + 'jaw' are literal and suggest a jaw that is locked, but the term refers to the medical condition tetanus, a specialized disease name not fully predictable from the parts.

Etymology

Lockjaw comes from the parts lock and jaw because the jaw becomes so stiff it seems 'locked' shut. That's why lockjaw is another name for tetanus, an infection that makes the muscles, especially the jaw, stay tight and hard to open.
