Few things are as intuitively obvious, yet philosophically challenging, as the existence of free will. There’s a fashionable critique of free will that says, “The very concept of free will is incoherent; therefore, it obviously doesn’t exist.” This article does not make the case for or against the existence of free will. Instead, it defends its conceptual coherence. Free will is not a nonsensical idea, and it might exist.
"free" will is redundant, and using the term might confuse us.
Simply take the singular concept of having a will and start reasoning from there.
