Dicky retires having eaten good roll (8)
I believe the answer is:
register
'roll' is the definition.
(I've seen this before)
'dicky retires having eaten good' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'having eaten' indicates putting letters inside.
'good' becomes 'g' (abbreviation).
'retires' anagrammed gives 'reister'.
'reister' enclosing 'g' is 'REGISTER'.
(Other definitions for register that I've seen before include "Written record of names, etc" , "New arrival at hotel will" , "Check in - catalogue" , "Record in writing" , "Offical roll of names" .)
