Theme or issue (5)
I believe the answer is:
topic
This clue is a double definition.
'theme' is the first definition.
(synonyms)
'issue' is the second definition.
(synonyms)
(Other definitions for topic that I've seen before include "might this be hot?" , "Subject (for conversation, etc)" , "Subject (eg, of text)" , "'Theme, subject (5)'" , "Talking point" .)
