Social climber put out, interrupted by celebrity (7)
I believe the answer is:
upstart
'social climber' is the definition.
(thesaurus)
'put out interrupted by celebrity' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'interrupted by' indicates putting letters inside.
'celebrity' becomes 'star' (I've seen this before).
'put' is an anagram of 'upt'.
'upt' placed around 'star' is 'UPSTART'.
(Other definitions for upstart that I've seen before include "Arriviste, parvenu" , "Person suddenly risen in world, and arrogant" , "Brash newcomer" , "Unexpectedly fresh" , "Person recently elevated and arrogant with it" .)
