Brought together, in a church service, English and Dutch (7)
I believe the answer is:
amassed
'brought together' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps you can see a link between them that I can't see?
'a church service english and dutch' is the wordplay.
'church service' becomes 'mass' (Mass is a type of church service).
'english' becomes 'E' (abbreviation).
'and' is a charade indicator (letters next to each other).
'dutch' becomes 'd' (common abbreviation).
'a'+'mass'+'e'+'d'='AMASSED'
'in' is the link.
Can you help me to learn more?
(Other definitions for amassed that I've seen before include "Gathered together" , "Accumulated, gathered" , "Mad seas (anag.)" , "Heaped up, accumulated" , "Accumulated over time" .)
