Limited or controlled in some way, often to prevent access or use by certain people or groups.
The restricted area is off-limits to unauthorized personnel.
Restricted → It is formed from "re-" (meaning back or again) and "strictus" (from Latin, meaning drawn tight or confined). The word "restricted" means drawn back or confined, indicating limitations placed on something.
Think of something being 'drawn tight' ('strictus') and 'back' ('re-') — this helps you remember that restricted means something is limited or confined.
