Okay, kiddo, let me try to explain what "free colchian" means.
Do you know what "colchian" means? It's actually a word that refers to people or things that come from a place called Colchis. Colchis is an ancient region that is now part of Georgia.
So, when we say "free colchian," it means that someone wants the people or things from Colchis to be free. But free from what, you might ask?
Well, sometimes people in power can try to control or take advantage of other people or places. And sometimes they might not let those people or places make their own decisions or live their lives the way they want to.
So, when people say "free colchian," they want the people from Colchis to have the freedom to live their lives the way they want to, without anyone else trying to control them.
Does that make sense, kiddo?
