Welcome something done about church parking (6)
I believe the answer is:
accept
'welcome' is the definition.
(thesaurus)
'something done about church parking' is the wordplay.
'something done' becomes 'act' (I've seen this before).
'about' is an insertion indicator.
'church' becomes 'ce' (abbreviation for Church of England).
'parking' becomes 'p'.
'ce'+'p'='cep'
'act' going around 'cep' is 'ACCEPT'.
(Other definitions for accept that I've seen before include "Consent to receive" , "Receive voluntarily" , "Agree or be willing to take" , "Welcome" , "Receive the gift or agree to comply" .)
