unknowledgeable
Not well informed
Unknowledgeable means lacking knowledge or information about something: He was completely unknowledgeable about cars.
The word suggests ignorance in a particular area rather than general stupidity.
It's the straightforward negative of knowledgeable, though *ignorant* or *uninformed* are more common choices.
