Groan moving church fixture (5)
I believe the answer is:
organ
'church fixture' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'groan moving' is the wordplay.
'moving' is an anagram indicator.
'groan' is an anagram of 'ORGAN'.
Can you help me to learn more?
(Other definitions for organ that I've seen before include "Heart or lung, say" , "Agency" , "Biological functionary" , "Publication - musical instrument" , "means for communicating information" .)
