The word "dredger" is derived from the verb "dredge", which originated in Middle English. The Middle English term "dregg" referred to the waste or sediment left at the bottom of a liquid, especially after the fermentation of wine or beer. This term can be traced back to Old English "dreg", meaning the dregs or sediment of a liquid. The verbform "dredge" emerged in the late 16th century, meaning to clear out or remove the sediment or unwanted material from the bottom of a body of water. Over time, the noun form "dredger" was formed to refer to the person or vessel involved in the process of dredging.
