adjective
changeable; volatile; fickle; flighty; erratic: a mercurial nature.
The English adjective mercurial ultimately comes from the Latin adjective mercuriālis “of or pertaining to Mercurius“ (i.e., the god Mercury), whose original function was as god of commerce, transporters of goods (especially of grain), and shopkeepers. Latin also has the plural noun, derived from the adjective, Mercuriālēs, the name of a guild of merchants. Mercurius is related to merx (stem merc-) “goods, wares, commodities” (and the ultimate source of English merchant and merchandise). By classical times Mercury was completely identified with the Greek god Hermes—the messenger of the gods because he was fast-moving, and always on the move, negotiating, fast-talking, making deals, flimflamming, playing tricks. Mercurius also acquired the meaning “pertaining to the planet Mercury” (Stella Mercuriī, “Star of Mercury,” a translation of Greek astḕr toû Hermoû), the fastest moving of the planets. Mercurial entered English in the 14th century in the sense “pertaining to the planet Mercury.”

noun
the deceptive tactic of simulating grassroots support for a product, cause, etc., undertaken by people or organizations with an interest in shaping public opinion: In some countries astroturfing is banned, and this includes sponsored blog posts.
Astroturfing was originally an Americanism, coined in 1974, meaning “to cover an area with Astroturf (a carpetlike covering made of vinyl and nylon to resemble turf, used for athletic fields, patios, etc.).” Twenty years later (1993) the current sense of Astroturfing “the deceptive tactic of simulating grassroots support for a product or cause, undertaken to influence public opinion” first appeared in Canadian and Australian newspapers.
An aide said Mr. Markey hoped to combat the tactic of astroturfing in which a professional lobbying effort is made to seem like a grass-roots movement.
This isn’t usually the sort of behavior we think of when we talk about political “astroturfing”—that much-loathed, much-feared practice of faking grass-roots support online—but as more and more political discourse has moved to the Internet, the techniques have multiplied.
an inferior poet.
Shakespeare (1564-1616) is the first recorded author to use balladmonger, a compound noun that has nearly always had a belittling or depreciatory sense. Monger is a common Germanic word derived from Latin mangō, “a slave trader; a merchant who adorns or decorates inferior wares to make them look more attractive.” From the Old English period even until the 20th century, monger has had positive connotations, but beginning in the mid-16th century monger and its derivative compounds frequently have had a negative connotation. For example, ironmonger “a merchant or dealer in iron and hardware,” first recorded in the 12th century, is neutral, but Mark Twain’s coinage superstition-monger is certainly depreciatory. Balladmonger entered English in the late 16th century.
