Thomas E. Payne's Describing Morphosyntax has been referred to by many as "the Conlanger's Bible", and I'll not dispute what that reference implies.

The first sentence of Amazon.com's description of Payne's book reads, "This book is a guide for linguistic fieldworkers who wish to write a description of the morphology and syntax of one of the world's many underdocumented languages." Well, guess what? Your conlang is an undocumented language, and you, the conlanger, are a linguistic fieldworker!

Even though this book is intended for linguists, I'd like to suggest that all conlangers will find Describing Morphosyntax an invaluable resource for two main reasons.

The first is that DM has a wealth of language data, and most of it comes from languages even many linguists haven't heard of. If you've ever thought to yourself, "Gee, this construction I've come up with looks a lot l!

Again, this book is intended for linguists, but I believe all conlangers (even those not linguistically-inclined) will find it, at the very least, useful.

I give it 10 out of 10 Lingwoes (A Lingwo is like a star--but better!)
