Just because I love arguing about free will, and because I feel like a lot of the time people are not all talking about the same thing when they say "free will"

Just because I love arguing about free will, and because I feel like a lot of the time people are not all talking about the same thing when they say "free will", would some of you be willing to tell me what you think "free will" means? Please say what you sincerely think free will means, and try not to give me strawman or devil's advocate positions on what you think your opponents think it means, if you would be so kind.
