What does it mean when a portscan shows a port as "tcpwrapped"?

I see tcpwrapper once in a while as a service, what does it mean?

"Run the NMAP as a root user.
It seems you have run Nmap scan as an unpriviliged user(i.e., not as a root user). when Nmap is ran as a non-root user it performs TCP scan for port scan. TCPwrapper is software at host machine which closes the TCP connection after three way handshake, when client has no access to a particular port. so run the nmap scan as a root user which uses SYN stealth scan for port scanning"
