Beef in a lasagne? Its potential selection is beyond dispute (5)
I believe the answer is:
final
'beyond dispute' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'beef in a lasagne? its potential selection' is the wordplay.
'FINAL' is hidden in amongst the letters.
But, I'm unsure how the hidden word is indicated.
'is' is the link.
Can you help me to learn more?
(Other definitions for final that I've seen before include "The last exam or leg of competition" , "big match" , "Like one's journey to cemetery" , "Coming at the end" , "Not to be altered" .)
