SQUIB: A person  with no magic ability born to magical parents.
 
Many squibs in the book don't carry wands. The quick spell course of study is a crock- if you have no magic ability you can't obtain this. You have to born with it, otherwise how do you explain purebloods and those with it who are considered muggle born (one of the parents is typically magical).
Squibs are not invited to study magic because they are unable, even with instruction, to do so. They are considered a disgrace to the wizarding world.
