seals off
Closes off entirely
Seals off means to close completely, preventing entry or exit.
A barrier seals off an area; authorities seal off a crime scene to preserve evidence.
The phrase suggests airtight or impenetrable closure: Police sealed off the building after the bomb threat.
Figuratively, someone might seal off their emotions—blocking access entirely.
