Hi,

An intermediate certificate is the certificate, or certificates, that go between your site (server) certificate and a root certificate.

The intermediate certificate, or certificates, completes the chain to a root certificate trusted by the browser.

Using an intermediate certificate means that you must complete an additional step in the installation process to enable your site certificate to be chained to the trusted root, and not show errors in the browser when someone visits your web site.

Root certificate

The root certificate is usually made trustworthy by some mechanism other than a certificate, such as by secure physical distribution. For example, some of the most well-known root certificates are distributed in the Internet browsers by their manufacturers.

a root certificate is either an unsigned public key certificate or a self-signed certificate that identifies the Root Certificate Authority (CA). A root certificate is part of a public key infrastructure scheme. The most common commercial variety is based on the ITU-T X.509 standard, which normally includes a digital signature from a certificate authority (CA).
