Year 1984: An archival experience of a year

Wicked

Originally signifying something evil or corrupt (originating from wicca, an Old English word for witch), that which was "wicked" soon became that which was cool. 19th century records show writers using the word as an adverbial synonym for "really" or "very".

From the 1960s through the 1980s, the word came to mean something else entirely. Emanating from Boston out into the rest of the United States, the slang word became a fixture of the English speaking world. 

But what about new jargon outside of slang? And what about outside the Anglo world entirely?
