Colin Gorrie is a linguist on a mission to bring linguistics out of the ivory tower. He is also a serial language learner. In trying to apply what he knew about linguistics to his language learning practice, he came across comprehensible input-based approaches. After seeing how well they worked, he became an evangelist for them too. Colin received his PhD in linguistics from the University of Arizona in 2014, where his studies focused on linguistic typology, the methodological foundations of linguistic theory, and Celtic linguistics. He is also an avid conlanger (maker of constructed languages). You can follow Colin on Twitter, YouTube, or through his website.
