Expanded problems are problems from past competitions which include not only the material from the competition (data, questions, solutions and mark-scheme) but also a detailed commentary on how to solve the problem, and suggestions for ‘taking it forward’ into a more general consideration of how language works (in other words, into the exploration of some small area of linguistics).
The following expanded problems are available:
- Danish: Danish numbers
- Estonian: What time is it in Tallinn?
- Japanese: Japaneasy
- Yolmo: Being with it in Yolmo
