A Way with Words is an informative and entertaining program/podcast, that explores word and language curiosities. Here is what I learned yesterday:
The word silly didn’t always have its modern meaning. In the 1400s, silly meant happy or blessed. Eventually, "silly" came to mean weak or in need of protection. Other seemingly simple words have shifted meanings as the English language developed: the term girl used to denote either a boy or a girl, and the word nice at one time meant ignorant.
