Merge associations with the same keys, same in a sense by user's definition

I know that it is the standard functionality of Merge to combine the values of the same keys among associations.



Now I would like to deal with a situation in which, in my associations, the keys are strings (English words). And I want to define the sameness as two words having the same result from WordStem so that "effects" and "effect" are the same key.



So is it possible for Merge to accept such a same test function for the keys, e.g., Equal@@WordStem[##]&, to determine what keys should be considered the same and be merged?



A MWE goes as below:



mergeFunc = x [Function] Total[#], Union[Flatten@#2] & @@ (x[Transpose]);

Merge["effects" -> 4, 1, 3, 5, mergeFunc]

Merge[>, <, mergeFunc]



<|"effect" -> 5, 2, 3, "effects" -> 4, 1, 3, 5|>

<|"effect" -> 9, 1, 2, 3, 5|>



The second result is desired.

    What about this?



    data = <|"effect" -> 5, 2, 3, "effects" -> 4, 1, 3, 5|>;
    Merge[
     KeyValueMap[key, value [Function] WordStem[key] -> value, data],
     mergeFunc

                      One-line joke

                      A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
