In grammar, an adjunct noun is an optional noun that modifies another noun; functioning similarly to an adjective, it is, more specifically, a noun functioning as a pre-modifier in a noun phrase.

From Rick and Morty S1:E8, Rixty Minutes.
Below are all nouns or noun phrases modifying the noun “Brothers”, see screenshot.  ➡️
  1. Alien Invasion (noun phrase)
  2. Tomato
  3. Monster
  4. Mexican Armada (noun phrase)

I checked out example titles of the real 60 Minutes and didn’t have much luck with the adjunct nouns. However, I did look at the universe that R&M inhabits, viz Netflix, and came  up with:

  • Prison Break
  • Vampire Diaries
  • Paradise PD
  • Chicago Party Aunt
  • Money Heist
  • Squid Game

being found in just one screen-full of movies … ⤵️
