Hectic rearranged tie hosted by European people - Hearts knocked out (8)
I believe the answer is:
frenetic
'hectic' is the definition.
(I've seen this before)
'rearranged tie hosted by european people hearts knocked out' is the wordplay.
I cannot really understand how this works, but
an anagram of 'tie' is 'eti' which is within the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for frenetic that I've seen before include "Extremely agitated -- if recent (anag)" , "Demented" , "Re-infect, being quite frenzied" , "Hectic" , "Lively" .)
