While Spock is generally known as, well, Spock, it's actually his last name. And what is his first name, then?
Answer It's unpronounceable
There isn't really any hard evidence on what Spock's first name is, as this topic has been continuously avoided by the franchise creators. However, the consensus is that Spock's Vulcan first name is simply incomprehensible to humans and, as such, usually omitted.
