Electra complex: too much sentimentality? (7)
I believe the answer is:
treacle
'too much sentimentality?' is the definition.
'treacle' can be an answer for 'sentimentality?' (treacle can mean sentimental speech). I am not sure about the 'too much' bit.
'electra complex' is the wordplay.
'complex' indicates an anagram.
'electra' anagrammed gives 'TREACLE'.
Can you help me to learn more?
(Other definitions for treacle that I've seen before include "Golden syrup" , "Something cloyingly sweet" , "refined product" , "flattery" , "Sticky fluid" .)
