What does mussel mean?
A mussel is a small, edible mollusk belonging to the bivalve group, meaning that its body is enclosed between two hinged shells. Mussels live in both saltwater and freshwater and are usually attached to submerged surfaces by tough, threadlike structures called byssal threads. They are commonly eaten throughout Europe, including in the Netherlands, France, Spain, and Portugal, and are also popular in North America. The plural of the word is mussels, with two l’s in standard British spelling; related inflected forms commonly appear as musselled and musselling. In culinary contexts, the word often appears with terms such as steamed mussels or mussel pasta, while mussel beds refers to an area where wild mussels grow abundantly. Although mussels and clams are both bivalves, they differ in shape, structure, and often in the ways they are prepared.

Where does mussel come from?
The word comes through Middle English from Old English muscle, which was borrowed from Latin musculus. Latin musculus could refer both to a muscle and to a mussel, probably because the shellfish resembles a small muscle. The modern English spelling with double s reflects the later Middle English form, while muscle continues to represent the related sense associated with physical strength.
