Adunicates

Well, adunicates is a word that doesn't really exist! Maybe you meant "advocates"? Advocates are people who really believe in something and want other people to believe in it too. So if somebody is an advocate for, say, recycling, that means they think recycling is really important and they want other people to recycle too. They might make posters or give speeches or write letters to try and convince other people to recycle. Does that make sense?
