What is the difference between もとづいて and もとづき


What is the difference between both of them? I could not find any explanations
so I came here.




The reason you could not find any explanation specifically about them is
because the difference can be explained as a generic difference between a te-
form and a masu-stem:

  * [なく vs. なくて and stem form vs. てform as conjunctions](https://japanese.stackexchange.com/q/2934/5010)
  * [Connecting phrases with the stem of masu-form](https://japanese.stackexchange.com/q/6412/5010)
  * [Stem of ます-form as conjuction](https://japanese.stackexchange.com/q/25921/5010)
  * [て versus combining-form for joining clauses](https://japanese.stackexchange.com/q/23789/5010)
  * [Is there a term for using conjugating verbs such that the sentence continues with another clause?](https://japanese.stackexchange.com/q/9771/5010)

Since もとづく is already a stiff verb, the difference between もとづいて and もとづき is
small, and they are interchangeable. Still, もとづき sounds relatively a little
stiffer or more academic.
