The word origins from 1520s. Its origin is uncertain, perhaps a variation of Middle French tremouille meaning “mill hopper”, in reference to the hopper’s constant motion to and fro – in a constant movement backwards and forwards or from side to side – (source also from Latin trimodia meaning “vessel containing three modii”, from modius, a Roman dry measure, related to modus meaning “measure”).
