Forget is a command which allows a wizard or witch to forget one or all of their remembered spells, thus freeing up mind space for other spells.
A witch can also use this command to forget squints or tricks that she has memorized.
Witches are taught this command by Nanny Ogg outside Granny Weatherwax's cottage.
Non witches and wizards are also able learn this command although it has no use.
