The program "grammartrainer.exe" is written in C, and designed to provide the user with exercises in Finnish morphology and some syntax. Each exercise selects 20 random and non-repeating questions from a much larger list of questions. The exercises cover the morphology that would typically be treated during the first year of studying Finnish (excluding, for the time being, non-finite verbs). Generally, exercises longer down the list will be more difficult than ones high up in the list. The program uses libraries specific to Windows. A Linux user is free to modify the source code to his own needs, but contact me first if you want to spread such a version! The program does not need installation. To use the program, just enter the number of the exercise you want to do. Entering number 31 will quit the program. After the exercise, any key will return you to the main menu. Note that entries are case-sensitive: avoid using capital letters. For any questions, contact me at: merlijn.de.smit@su.se Have fun learning Finnish!
