ACADEMIC 

Filibuster - The word is a derivation from the Dutch vribuiter which means "freebooter or pirate." Originally, filibuster was used in American English to describe gun-runners in Central America, men who engaged in war with a country with whom their own country was at peace. Eventually, the meaning of the word evolved into "obstruction of legislation in the U.S. Senate by prolonged speechmaking," after a congressman described one such obstruction as "filibustering against the U.S."  Source

Fiscal - The word fiscal originated in Ancient Rome. Merchants used small baskets made of rush or reed -- consequently named fiscus--to carry money. These fiscus baskets were so common in Rome that the national treasury was named the fisc. Over centuries, anything that had to do with money matters came to be called fiscal.  Source
