Joke I'd spun with attempt to show expertise (8)
I believe the answer is:
punditry
'show expertise' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'joke i'd spun with attempt' is the wordplay.
'joke' becomes 'pun' (pun is a type of joke).
'spun' is a reversal indicator.
'with' means one lot of letters go next to another.
'attempt' becomes 'try' (synonyms).
'id' in reverse letter order is 'di'.
'pun'+'di'+'try'='PUNDITRY'
'to' is the link.
Can you help me to learn more?
(Other definitions for punditry that I've seen before include "expert opinion" , "The giving of expert opinions" , "display of expertise" , "The ability to speak authoritatively on a subject" .)
