More about decussate

The verb decussate “to cross in the form of an X; intersect,” comes from Latin decussāt-, the inflectional stem of decussātus, the past participle of the verb decussāre “to mark with a cross or an X.” Decussāre is a derivative of the noun decussis “a bronze ten-piece coin; the number ten, a decade; an X-shaped mark” (X was the Latin symbol for 10). Decussis is a reduced form of decem “ten” and as (also assis) “a copper coin or monetary unit; a penny.” Decussate entered English in the second half of the 17th century.

More about pharaonic

The adjective pharaonic, “pertaining to or like a Pharaoh; impressively or overwhelmingly large,” is a derivative of the noun Pharaoh. Pharaoh comes via Late Latin Pharaō (inflectional stem Pharaōn-) from Greek Pharaṓ (inflectional stem Pharaōn-), from Hebrew parʿō, from Egyptian prʿʾ (probably pronounced like the Hebrew parʿō) “great house” (the order is the noun pr-, then the adjective ʿʾ). In Egyptian pr-ʿʾ was not the name of a Pharaoh, but the name of a Pharaoh’s (palatial) residence, very like our own “The White House.” Pharaonic entered English toward the end of the 18th century.

a clever, unscrupulous person.

More about snollygoster

Snollygoster “a clever, unscrupulous person,” is an American slang term that first appears in print in 1845 in Marion County, Indiana. As with many, if not most slang terms, there is no reliable etymology for the word. Some authorities have suggested that snollygoster is a variant of snallygaster, a mythical monster that preys on poultry and children and is supposedly found in Maryland, but the earliest citation for snallygaster is 1940, nearly a century after snollygoster.

how is snollygoster used?

But the people will awaken, and all that will be left of the snollygoster will be an unsavory blotch on the history of American politics.

Fred L. Carr, "College Record," North Carolina University Magazine, November 1893
