incompetent
Lacking basic ability
Incompetent describes someone who lacks the skill, ability, or qualification to do something adequately.
An incompetent employee makes frequent mistakes or cannot perform basic job functions.
The word often carries legal weight: a court may declare someone mentally incompetent, meaning they cannot manage their own affairs or stand trial.
As a noun, an incompetent is a person who fits this description: The department is run by incompetents.
The word suggests not just inexperience but fundamental inability.
