What is "free will"?

What's the definition?
Does it exist?

"Free will" is a frame to recognize causality between mental state and action.

Sense of Agency

https://en.wikipedia.org/wiki/Sense_of_agency

The sense of agency (SA), or sense of control, is the subjective awareness of initiating, executing, and controlling one's own volitional actions in the world.[1] It is the pre-reflective awareness or implicit sense that it is I who is executing bodily movement(s) or thinking thoughts.

Will

something which initiate new actions or new mental state

  • intention
  • volition
  • voluntary
  • urge
  • impulse
  • drive
  • desire
  • decision
  • deliberation
  • motivation

What is "free-ness" of free will?

What I do or what I think is decided or initiated by myself.
= free

What I do or what I think is not decided or initiated by myself.
= not free

Is this right?

What I decide is not decided by myself consciously and intendedly.

Will is abruptly given.

We don't intend to create what kind of will we are going to make.
Some thoughts, wills, impulses, urges, desires or other motivations of actions are given without deliberate conscious process,
and we accept it as ourselve's will.
We obey the will.
We are barely aware of such connection of pop-out thoughts and acceptance explicitly.
It supports "Free-ness" of free will.
