Great concept
Yes, it would be nice to be able how to use words in a sentence. The app is not particularly user friendly. I suggest the opening screen have some colored buttons with words to tap on to find example sentences. Another idea would be to be able to type any word & search & have sample sentences appear. Declutter the screen so that there is less to choose from in each screen. Too cluttered. Design it so easy that an elementary aged child could navigate it easily. Just trying to be helpful. Good luck! 🍀
