Some European runs to cradle head of collapsed ballerina (6)
I believe the answer is:
dancer
'ballerina' is the definition.
(I've seen this in another clue)
'some european runs to cradle head of collapsed' is the wordplay.
'some european' becomes 'e' (abbreviation e.g. EU).
'runs' becomes 'r' (cricket abbreviation).
'to' says to put letters next to each other (I've seen this in other clues).
'cradle' becomes 'dan' (I can't justify this - if you can you should give a lot more credence to this answer).
'head of' suggests taking the first letters.
The first letter of 'collapsed' is 'c'.
'e'+'r'='er'
'dan'+'c'='danc'
'er' put after 'danc' is 'DANCER'.
Can you help me to learn more?
(Other definitions for dancer that I've seen before include "Entertainer" , "''I hope you have the feet of a ...'' (Charlie McGettigan)" , "One in the same team as, say, Rudolf" , "Terpsichorean" , "Ballet performer" .)
