Acid came out for researcher (8)
I believe the answer is:
academic
'researcher' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'acid came out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'acid'+'came'='acidcame'
'acidcame' with letters rearranged gives 'ACADEMIC'.
'for' is the link.
Can you help me to learn more?
(Other definitions for academic that I've seen before include "Scholar - of no practical importance" , "having no bearing on the situation" , "what's not relevant" , "Intellectual" , "One that's learned" .)
