That book os phenomenal. It's what got me to spend most of my undergrad time researching constructed languages.

Well I got my bachelors in linguistics, and I'm still working towards working in the field. I'm just going at it from a different field now due to funding. I mostly research how we learn languages and what mechanisms can be utilized to be the most effective.

If you want any good intro reads into the subject, I'm more than happy to recommend!
