Hard getting permit to worship (6)
I believe the answer is:
hallow
'worship' is the definition.
(thesaurus)
'hard getting permit' is the wordplay.
'hard' becomes 'h'.
'getting' says to put letters next to each other.
'permit' becomes 'allow' ('allow' can be a synonym of 'permit').
'h'+'allow'='HALLOW'
'to' is the link.
(Other definitions for hallow that I've seen before include "Make holy" , "Consecrate" .)
