I've been trying to find a website or dictionary that gives students the word classes/families. I haven't been able to find one. Most dictionaries would give suggestions of other related words. Some are part of the word family of the word you're viewing, some are not.
When I teach my students about finding out the word families, they can't do it because they don't have a place to go to. I always have to tell them the word families.
Do you have any idea where I can find such a website or resource?
By Word Families, I mean if my student is studying "participate" (V), I also want them to find out the other word family members - "Participation" (n), "participative", etc.
I'm afraid that online dictionaries that I know don't do that thoroughly.
