Morphology

thermocouple = couple (semi-transparent) = thermo + couple

The structure is clear as 'thermo-' plus 'couple', but the term denotes a specialized measuring device rather than an ordinary pair.

Etymology

The word thermocouple comes from thermo- meaning 'heat' and couple meaning 'a pair' or 'to join'. So a thermocouple is literally a joined pair of different metal wires that makes a small electric voltage when their joined ends are at different temperatures, and that voltage lets you measure temperature.
