Morphology

subdomain = domain (transparent) = sub + domain

The prefix 'sub-' clearly indicates a smaller or subordinate part of a larger 'domain'.

Etymology

Subdomain comes from the parts sub- 'under' and domain 'area' or 'territory'. So a subdomain is a smaller section 'under' the main domain, which is why websites use subdomains for parts like a blog, support page, or a department site.
