abyssal

Merriam-Webster's Word of the Day for February 3, 2017 is: abyssal • \uh-BISS-ul\  • adjective 1 : of or relating to the bottom waters of the ocean depths 2 : impossible to comprehend : unfathomable Examples: "Since the accident, researchers from the Guangzhou Institute of Oceanology have mapped several deep eddies in the Xisha Trough, an area of abyssal ocean off Hainan." — David Hambling, The Guardian (UK), 29 Dec. 2016 "I'm referring to something that was revealed when the federal opposition parties were talking about a coalition government: The abyssal ignorance, even in parts of the media, about how our own parliamentary system works." — Josée Legault, The Gazette (Montreal), 26 Dec. 2008 Did you know? Abyssal is a relatively rare word, though it's derived from the more prevalent noun, abyss. In contrast, the adjective abysmal is more common than its corresponding noun abysm. All four terms descend from the Late Latin word abyssus, which is in turn derived from the Greek abyssos ("bottomless"). Abyss and abysm are synonymous (both can refer to the mythical bottomless pit in old accounts of the universe or can be used more broadly in reference to any immeasurably deep gulf), but the adjectives abyssal and abysmal are not used identically. Abyssal can mean "incomprehensible" (as in "showed abyssal ignorance") but it's most often found in contexts referring to the bottom of the sea. Abysmal shares the oceanographic sense with abyssal, but it more frequently means "immeasurably great" or "absolutely wretched."
