Opening serve may produce either outcome (5)
I believe the answer is:
issue
I believe this is a quadruple definition!!
'opening' is the first definition.
(I know that issue is a type of opening)
'serve' is the second definition.
(thesaurus)
'may' is a link.
'produce either' is the third definition.
'issue' can be an answer for 'produce' (I've seen this before). I am not certain of the 'either' bit.
'outcome' is the fourth definition.
(I know that outcome can be written as issue)
Can you help me to learn more?
(Other definitions for issue that I've seen before include "Difficulty" , "Offspring or one of publication" , "that may be taken where there's disagreement?" , "Topic (to be addressed)" , "Edition of a publication" .)
