Secret Life of Words: English Words and Their Origins

Open the Oxford English Dictionary and you'll find dead words such as "wittol" and distinctly contemporary words such as "ginormous" and "multislacking." In addition to looking at the lifespan of words from birth to death, this lecture also considers "semantics" - the study of how words mean what they mean.

Go behind the scenes of the world's dictionaries and see the very human decisions that go into creating them. Lexicographers tend to take a descriptive approach to language and study how we use words, including slang. But as readers, we turn to the dictionary for a prescriptive guide on how we should use words.

Look at the history of the English dictionary over the past 400 years, culminating with today's online resources. You'll meet the likes of Samuel Johnson and Noah Webster, discover the origins of American spellings, and hear the story of how the monumental OED was created.

Did you know that "girl" used to mean "a child of either sex" or that "nice" used to mean "silly, foolish"? While some words are remarkably stable, many undergo semantic shifts. This lecture surveys the five major categories of semantic change: generalization, narrowing, amelioration, pejoration, and metaphorical extension.

Humans love to play with words, whether it's to better express what we have to say or to show off a personal style. Study the ways in which new words are created, from combining, shortening, and functional shifts to blends, back formation, and reduplication. This rule-governed creativity gives us everything from slang to technology jargon.
