I finished "In the Land of Invented Langauges" by Arika Okrent this morning.
I highly recommend it to anybody who is interested in languages or linguistics. She goes through the history of constructed languages more or less chronologically, mainly focusing on a few highly influential ones. It's not a stuffy book about analyzing grammar (although there is some of that). Instead, it's told from a very human perspective. Why did these languages creators do what they did? Who where they? How were they influenced by those that came before?
It's not a humor book, but I found certain parts funny - like when she tried to translate "shit" into a very obtuse language from 1668.
If you like language, it's a kind of cozy feel-good book about the human condition.
