.com is not a full word either (company), or .org (organization), .net (internet), .gov (government), ...
My preferred reading is .com for commonlymisinterpretedbypeoplewhodonotreadrfcsbutitdoesnotmatterintheslightest, which is a Welsh word meaning "oddly shaped sheep".
> Commercial, any commercial related domains meeting the second level requirements.
EDIT: Looks like I misunderstood what Google having .dev meant in the above discussion; domains using it are available to purchase through their registrar (or more precisely resellers since I guess they don't sell directly anymore)
