In pieces like subordinate? (7)
I believe the answer is:
asunder
'in pieces' is the definition.
(asunder means torn apart)
'like subordinate?' is the wordplay.
'like' becomes 'as'.
'subordinate?' becomes 'under' ('under' can be similar in meaning to 'subordinate').
'as'+'under'='ASUNDER'
(Other definitions for asunder that I've seen before include "Let no man put -" , "(Break) apart" , "(Torn) into parts" , "(Broken) apart" , "Sad rune (anag.)" .)
