Difference between "expurgation" and "censorship"
As a language would not make two different words for one phenomenon, there must be a difference between expurgating something and censoring it, even a slight, subtle one. So which one is more appropriate in which context?

Question

Answer

The difference is that expurgate is not a common word.

Answer

The difference between expurgate and censor is that expurgate is to edit out rude, incorrect, offensive, useless, or otherwise undesirable information from a book, cd or other publication. To censor is to review in order to remove objectionable content from correspondence or public media, either by legal criteria or with discretionary powers.
