Oh, these puzzles are challenging!!
From the website:
“The Linguistics Challenge was a fun and educational activity designed for secondary school students (ages 12 through 18). University students and other adults also find these materials interesting and challenging. The idea is to solve puzzles in languages you have never studied or learned. “
I completed the first one, Agta, after several false starts. I treated the words as if they were like Greek combining forms–two parts with meanings of their own, but needing to be combined a certain way for a different meaning. If you want a hint, comment on this post and I’ll give you one!
