Compliant bit done badly traps leader in enigma (8)
I believe the answer is:
obedient
'compliant' is the definition.
(associated in meaning)
'bit done badly traps leader in enigma' is the wordplay.
'badly' is an anagram indicator (letters in the wrong order).
'traps' is an insertion indicator.
'leader in' indicates taking the first letters.
The first letter of 'enigma' is 'e'.
'bit'+'done'='bitdone'
'bitdone' with letters rearranged gives 'obedint'.
'obedint' placed around 'e' is 'OBEDIENT'.
(Other definitions for obedient that I've seen before include "A good dog should be" , "Deferential" , "Submissive, biddable" , "Complying with orders" , "Docile" .)
