This ROOT-WORD is the Prefix INTRA which means WITHIN. Notice how similar it is to INTER. Notice how careless pronunciation makes them sound almost exactly alike. The meaning is very different. In ancient days every city had a protective wall around it. Within the wall meant with the city. That is why sports or events within one city are still called INTRAmural.
