Studies in Words is a work of linguistic scholarship written by C. S. Lewis and published by the Cambridge University Press in 1960.[1][2] In this book, Lewis examines the history of various words used in the English language which have changed their meanings often quite widely throughout the centuries.Lewis's motivation for writing the book was in explaining to students of the work of previous centuries that the definition of a word that they already think they know (his dangerous sense, which he abbreviates D.S.)The words studied are nature, in all its phrases, especially "human nature"; sad, which originally meant "heavy"; wit; free, with all its differences from slavery and villainy; sense, with its two meanings of perception and judgement; simple; conscience and conscious; world; and life; with also the phrase "I dare say!"[4] William G. Moulton praised the book as "readable, informative...and witty" but also criticized it as "amateurish", and stated that it had little to offer professional linguists beyond "a delightful style and many well-chosen examples".
