Praise be! Electra complex! (9)
I believe the answer is:
celebrate
'praise' is the definition.
(thesaurus)
'be electra complex' is the wordplay.
'complex' is an anagram indicator.
'be'+'electra'='beelectra'
'beelectra' is an anagram of 'CELEBRATE'.
(Other definitions for celebrate that I've seen before include "Honour; make famous" , "Mark an important occasion with festivities" , "Stage a special festivity" , "Rejoice - observe - perform" , "Have a party in honour of" .)
