adunatos marks what cannot be done or what a person is unable to do, including bodily incapacity.

The prevailing use marks an action, condition, or matter as not possible, especially in statements contrasting human limitation with what is possible with God or describing what cannot occur. A smaller personal use describes bodily incapacity and those characterized as weak.

1. Not possible or cannot be done · dominant

   The neuter forms occur in impersonal statements of impossibility: in Hebrews 10:4 the APB renders the clause "it is impossible for the blood of bulls and goats to take away sins," while Hebrews 11:6 says that without faith "it is then impossible to please God." In Luke 18:27, Mark 10:27, and Matthew 19:26, the clause contrasts what is impossible with humans and possible with God; Hebrews 6:18 likewise places the term in the statement that it is impossible for God to lie.

In the Anselm Project Bible: Across the impersonal clauses, the APB commonly uses "impossible," including statements about taking away sins, pleasing God, and human limitation. In personal contexts it uses "unable" and "weak," but the translation does not mark a fixed English equivalent for each form.
