Elements of dance chosen — it precedes foxtrot (4)
I believe the answer is:
echo
'it precedes foxtrot' is the definition.
(in the NATO phonetic alphabet)
'elements of dance chosen' is the wordplay.
'elements of' indicates a hidden word (elements or parts of the clue).
'ECHO' can be found hidden inside 'dance chosen'.
(Other definitions for echo that I've seen before include "repercussion" , "repetitive" , "Radio operator's word for 'E'" , "She loved Narcissus - it's recalled" , "Mimic" .)
