Adherent's record pile dislodged (8)
I believe the answer is:
disciple
'adherent's' is the definition.
(synonyms)
'record pile dislodged' is the wordplay.
'record' becomes 'disc' (eg a CD, compact disc).
'dislodged' indicates anagramming the letters.
'pile' is an anagram of 'iple'.
'disc'+'iple'='DISCIPLE'
(Other definitions for disciple that I've seen before include "A follower or apostle" , "A faithful follower, as of Christ (8)" , "Mark, for example" , "Christian?" , "I spliced to get a follower" .)
