Noun A + の + Noun B and Noun B + Noun A


I learned yesterday from [Function of の particle in the title
「進撃の巨人」](https://japanese.stackexchange.com/questions/12658/function-
of-%e3%81%ae-particle-in-the-
title-%e9%80%b2%e6%92%83%e3%81%ae%e5%b7%a8%e4%ba%ba?rq=1) about one usage of
the の particle, an example being 友達のコジ. I understand this as "(my) friend
Koji". I also know that if you want to say "teacher Koji", you use コジ先生. I
have two connected questions:

  1. Can you say 先生のコジ? If yes, does it mean the same as コジ先生?
  2. Can you say コジ友達?




先生 is a noun that also works as a name suffix. In English, there are name
prefixes which you can add _before_ someone's name (e.g., _Mr._ Smith,
_Professor_ Smith, _Doctor_ Smith). In Japanese, there are various name
suffixes you can add _after_ someone's name, and 先生 is one of them. On the
other hand, 友達 is just a noun.

  1. Yes 先生のコジ is correct but it's different from コジ先生. The former is like "Koji, the teacher", while the latter is like "Mr. Koji".
  2. No, you can't say コジ友達 because 友達 is not a name suffix.
