To formally accuse of or charge with a crime, especially by the finding of a grand jury.
From Anglo-French 'enditer' (to accuse, to write down), from Old French 'enditier,' a variant of 'indicter,' ultimately from Latin 'indīctāre,' a frequentative of 'indīcere' (to proclaim, to declare against), from 'in-' (upon, against) + 'dīcere' (to say, to speak).
