Root Explanation

Dredger → It is formed from "dredge" (from Middle English *dreggen*, meaning to clear a channel or remove sediment) and the suffix "-er" (meaning a person who performs an action). A dredger is a person or machine that clears or removes material from a body of water.

Memory Tip

Think of someone who 'clears' ('dredge') a waterway — the '-er' indicates that this person is doing the action. This helps you remember that a dredger is someone who removes sediment from water.
