Type: Spell
Pronunciation: cul-loh-POR-tus
Description: Locks doors, and presumably all things that can be locked; it is unknown whether the counterspell is required, or if a key could open it.
Seen/Mentioned: Used by Hermione Granger in 1996 in an attempt to prevent the Death Eaters that were following her from catching up.
Etymology: Perhaps a portmanteau of Latin word Colligere, which means "gather" and porta, which means "gate".
Notes: This spell can easily be countered with Alohomora.
