Mew is a user interface for text messages, multimedia messages (MIME), news articles and security functionality including PGP, S/MIME, SSH, and SSL. Also, Mew can work with the recent search services.

Mew is an acronym for "Messaging in the Emacs World". You should spell it with the first letter capitalized and pronounce it as it is (i.e. the meow of cats). When the author started programming it, he chose a cute word from his English dictionary. Thus, Mew.
