Wordslut

Read this for a history of The Man holding women down with a dictionary; an explanation of vocal fry and upspeak, the roles they fill in female communication, and how vilifying them is part of a hate as old as time; the many grammatical roles that an f-bomb can play; why gay guys often sound gay but lesbians don't sound 'lesbian'; and the word 'slut'. A lot. Just read it.

Edit: I originally rated Wordslut at four stars, but on reflection, its combination of outrage and history, delivered with disarming humor, sets a bar that should be considered the gold standard, not the silver standard.

In many ways, I ought to have been a linguistics (or biochem) rather than mathematics major in college! Language is so important (and fascinating) to a society, including how it reflects the society and the workings of the society overall and how it changes year to year (decade to decade) to reflect said society as it does so.
This book discusses the language and linguistics of the US and their effect on, and more precisely how they are affected by sexism and prejudice exhibited by our nation. It discusses more than just the language and linguistics themselves, but the underlying prejudices displayed by them, and some of what we currently ARE doing and should encourage to help offset some of the negative impacts.
