I have a phrase "X and Y are systems that are dependent on each other and affect each other".

I want to rephrase this to "X and Y are interdependent and ???? systems"

Is there a suitable adjective? perhaps "mutually ???"

    One might say two such systems are codependent. At least some people would. Dec 21 '16 at 13:49

    dependent implies affect. "X and Y are interdependent" is enough.

  • One could use entwined or entangled thus, at the risk of perpetrating a metaphor from quantum physics. Dec 21 '16 at 15:18
  • interdependent works on its own, but if you want a synonym then maybe linked or affiliated

The solution I found was "interacting". This might not be the most suitable for all contexts, but worked best for me.

So "X and Y are interacting and interdependent systems"


Corresponsive is a possibility. According to Merriam-webster, it means 'mutually responsive' which seems pretty close to what you are looking for.


  • Ill do that when I get a chance, but just for the record I cant make comments yet, otherwise this would have been one. Apr 21 '17 at 19:15
  • I think all of these only mean that they act together, not that they act on one another. Apr 21 '17 at 20:13
  • @HenryBrice I removed two of my suggestions that on second review, I agree with you about. Added a source for corresponsive, which think is a better answer. Apr 21 '17 at 20:20
