Canonify is the process of making something canonical. In computers, it can mean "making something conform to a standard" or "getting at the root of something".

For example, if you want the FQDN (Fully Qualified Domain Name) of an IP address or non fully qualified domain name, you might use DNS to canonify the IP address or non fully qualified domain name in order to get the FQDN.

Canonify is often used when describing email processing. For example, if a local user sends an email to "jane", the mail server has to canonify the address "jane" into a proper email address ("jane@host") before it can decide how to deliver it.

Canonicalization has the same meaning as canonify, and may actually be the more popular usage.
