Apart from some enigmas, understood (7)
I believe the answer is:
asunder
'apart from' is the definition.
(thesaurus)
'some enigmas understood' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ASUNDER' is hidden within 'enigmas understood'.
(Other definitions for asunder that I've seen before include "being in two" , "(Split) into pieces" , "separately" , "Apart - in pieces" , "(Torn) into parts" .)
