Where one might see sense after reading judgement (9)
I believe the answer is:
thesaurus
'judgement' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'where one might see sense after reading' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'the' (both can introduce a definite example of something) and 'the' is found within the answer.
'reading' could be 'r' (one of the traditional three R's of education) and 'r' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for thesaurus that I've seen before include "Wordy book" , "Word book" , "lists?" , "Book of words with synonyms, antonyms etc" , "Book listing synonyms" .)
