Student or Learner
I saw this sentence:
... has become increasingly skill-and experience-based.
Should it be skill-and-experience-based or skill-and-experience based?
What's the rule about writing such words comprising several other words combined?
Thank you in advance.
There is nothing complicated. It is simply omitting the word "based" in order to avoid repetition. The same can be applied to any repetitious phrase:
The money market is bedevilled by over- as well as under-subscriptions.
