Etymology: A lightship is exactly what its name says: a ship that carries a light. Anchored over shoals, sandbanks or rocks where a lighthouse could not be built, it showed its lamp so that sailors knew where danger lay and where the safe channel ran. The compound is a plain combination of "light" and "ship," with no metaphor or special coinage behind it. The word has close relatives in the North Sea trading world. Middle Low German had "lüchteschip," and Dutch today has "lichtschip," both meaning the same thing. That shared pattern suggests the idea of a floating beacon grew up among the seafaring peoples of the Low Countries and northern Germany, and English took the same two-part construction. The English form is therefore a straightforward compound built from familiar parts rather than a borrowing.

Synonyms: beacon, lighthouse
