I have heard that humans have a *limited* or *constrained* free will, especially when biological limitations are brought up. However, Merriam-Webster dictionary says:

>**Limited**

>1a: confined within limits: **RESTRICTED**

And:

>**Constrain**

>1a: : to force by imposed stricture, **restriction**, or limitation

However, among the many definitions of *free* is:

>**Free**

>8a: **not** obstructed, **restricted**, or impeded

Does this mean *limited free will* is the same as **restricted unrestricted will**? 

What is *limited free will*?
