Feeling excited about new issue raised (9)
I believe the answer is:
sentiment
'feeling' is the definition.
(sentiment is a kind of feeling)
'excited about new issue raised' is the wordplay.
'excited' becomes 'sent' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'new' becomes 'n'.
'issue' becomes 'emit' (I've seen this before).
'raised' says the letters should be written in reverse.
'n'+'emit'='nemit'
'nemit' in reverse letter order is 'timen'.
'sent' going around 'timen' is 'SENTIMENT'.
Can you help me to learn more?
(Other definitions for sentiment that I've seen before include "View, opinion, feeling" , "General feeling" , "Mawkishness" , "Slush" , "judgement" .)
