Some perfectly normal words are not accepted in my language
We're aware of some issues in the dictionaries we use for the language games and we are improving the dictionaries for all of our languages but this is an ongoing project.
Note though that proper nouns are not accepted as valid words in Word Fresh and Word Path. This includes names of cities, rivers etc. In Word Path words can only be constructed from left to right and top to bottom, whereas in Word Fresh, words can be constructed in all directions (including diagonal and in changing directions).
