what is a squib harry potter

A squib in Harry Potter is a non-magical person who is born to at least one magical parent. They have no magical abilities themselves, unlike their wizard or witch family members. Squibs are essentially "wizard-born Muggles" — they come from magical families but cannot perform magic. Despite this, they can see magical creatures, enter places hidden from Muggles, and participate in wizard society to some extent. However, they often face discrimination and are sometimes forced to live more among Muggles than wizards. Notable squibs in the Harry Potter series include Argus Filch, the caretaker of Hogwarts, and Arabella Figg, a caretaker who watches over Harry Potter during his childhood.
