Mercurys

Mercurys is the plural form of Mercury used mainly to refer to multiple things that bear the name Mercury. It is not a standard term for a single object and is encountered primarily in proper names or when the context requires indicating several Mercury-named items. Because Mercury itself refers to different concepts across domains, the plural form is infrequently used outside of lists or brand names.

In astronomy, Mercury is the innermost planet of the Solar System. Because there is only one planet named Mercury, the plural Mercurys is not used to describe it.

In chemistry, mercury is the metallic element with the symbol Hg. When discussing multiple quantities, writers typically specify the amount (for example, two kilograms of mercury) rather than using a plural form of the noun Mercury. The plural Mercurys would be unusual and is generally avoided in scientific contexts.

In mythology, Mercury is the Roman messenger god. As with the planet, the standard practice is to refer to a single deity; Mercuries would only appear in contexts that imagine or name multiple figures titled Mercury.

In industry, Mercury was the name of a long-running Ford division that produced cars from 1939 to 2011. In that sense, Mercurys can refer to multiple Mercury-brand vehicles or models, though writers usually specify the model names (such as Grand Marquis or Sable) rather than using the plural.

Outside of these domains, Mercurys may appear in titles, brand names, or proper nouns. In most cases, using Mercury with a clear descriptor is preferred to avoid ambiguity.
