Noun の Noun

No (の)is a particle that connects two nouns

Examples:
たけしさんのでんわばんごう - Takeshi's phone number
Takeshi san no denwa bangoo

だいがくのせんせい - a college professor
daigaku no sensei

にほんごのがくせい - a student of the Japanese language
nihongo no gakusee

にほんのだいがく- a college in Japan
nihon no daigaku

The main idea in the Japanese language always comes at the end, with any further description place before it.

By using no with two nouns, it is more or less like using one big noun
