subdomain
Site address prefix
A subdomain is a division of a larger domain, appearing as a prefix before the main domain name: blog.example.com, where "blog" is the subdomain.
Websites use subdomains to organize distinct sections—mail, shop, support—without registering separate domains.
More broadly, subdomain describes any specialized area within a larger field: Phonetics is a subdomain of linguistics.
