So if you buy a physical Bitcoin for example, you'll notice they have a private key printed on them and the guy who created them knows that key. Typing your own twelve words will probably not work how you expect, since the words require a particular structure (the last word is a checksum). The BIP32 algorithm extends the aforementioned approach introducing the concept of the extended key, defined as the concatenation of the root private key of 256 bits, S root, and the chain code of 256 bits, c, that is (S root;c). A private key is a random number that uses a one-to-one mathematical function to generate a public key. Why?
