According to Cistercian legend, a little devil called
Tutivillis would collect any words ‘dropped’ by monks celebrating
the Office. The devil gathered these missed words in his bag which he
then brought to his master, Brother Accuser, who duly punished the offenders.
Fear of this tell-tale would have surely been an incentive to the monks
to repeat every word clearly.
