'On the other hand, many words were refashioned to reflect their Latin or Greek etymology. For example, for "debt" early Middle English wrote det/dette, with the b being standardized in spelling in the 16th century, after its Latin etymon debitum; similarly for quer/quere, which was respelled as choir in the 17th century, modelled on Greek χορός chorus; in both cases, the pronunciation was not changed.'
