1. Think of five related words in a given semantic field, e.g. very, really, extremely, completely, totally or sick, ill, infirm, unwell, unhealthy, etc. (Feel free to use a thesaurus if you'd like: 1 2 3).
2. Use Google Books (155 billion words, 1810-2009), COHA (400m words, 1810-2009), the TIME Corpus (100m words, 1923-2006), and COCA (425m words, 1990-present) to examine the historical trajectory of these five related words over time. Please use charts to show frequency over time-- preferably all words on one chart.
Two other questions:
-- What were the methodological issues involved in using these corpora?
--In COCA, how are the historical shifts related to variation between genres?
