Gravedigger has lewd message being broadcast (6)
I believe the answer is:
sexton
'gravedigger' is the definition.
(thesaurus)
'lewd message being broadcast' is the wordplay.
'lewd message' becomes 'sext' (I have seen 'Explicit message' mean 'sext' so perhaps 'message' could also mean 'sext'. I am not sure about the 'lewd' bit.**).
'being broadcast' becomes 'on' (I've seen this in other clues).
'sext'+'on'='SEXTON'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for sexton that I've seen before include "They went and told the -, and / The - tolled the bell (Thomas Hood)" , "Graveyard employee" , "One looks after church and churchyard" , "parish factotum" , "Church official" .)
