A small opening in a lock where a key is inserted to open or close it.
She peered through the keyhole to see who was at the door.
Keyhole → It is formed from "key" (from Old English *cāg*, meaning a device used to open a lock) and "hole" (from Old English *hol*, meaning an opening or hollow space). The word "keyhole" refers to the opening in a lock where a key is inserted.
Think of a 'key' that fits into a 'hole' — that's how you remember that a keyhole is the opening for a key.
