Suggestion from good master of ceremonies (5)
I believe the answer is:
ghost
'suggestion' is the definition.
(I know that ghost is a type of suggestion)
'good master of ceremonies' is the wordplay.
'good' becomes 'g' (abbreviation).
'master of ceremonies' becomes 'host' (synonyms).
'g'+'host'='GHOST'
'from' is the link.
(Other definitions for ghost that I've seen before include "Write for another" , "suggestion" , "Author, secretly" , "Phantom" , "insubstantial presence" .)
