Ghost finds journalist enthusiastic (8)
I believe the answer is:
spirited
'enthusiastic' is the definition.
(associated in meaning)
'ghost finds journalist' is the wordplay.
'ghost' becomes 'spirit' (I've seen this before).
'finds' says to put letters next to each other.
'journalist' becomes 'ed' (short for editor).
'spirit'+'ed'='SPIRITED'
(Other definitions for spirited that I've seen before include "Secretly transported" , "Lively and brave" , "Riptides of lively kind" , "Lively, in upbeat mood" , "with brio" .)
