dredged

Dredged is the past tense of dredge, which has two distinct meanings.

One involves clearing or deepening waterways by scooping up mud, silt, or debris from the bottom: They dredged the harbor to accommodate larger ships.

If you dredge up something, you bring it to the surface, often unpleasant memories or forgotten information: Why dredge up the past?

The other dredge belongs to cooking: to coat food lightly in flour, breadcrumbs, or sugar before frying or baking.
