Church reader, fast one, keeps time (9)
I believe the answer is:
gospeller
'church reader' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'fast one keeps time' is the wordplay.
'fast one' becomes 'goer' (I am not sure about this - if you are sure you should believe this answer much more).
'keeps' means one lot of letters goes inside another (inserted letters are kept inside).
'time' becomes 'spell' (both can mean a short period of time).
'goer' going around 'spell' is 'GOSPELLER'.
Can you help me to learn more?
(Other definitions for gospeller that I've seen before include "religious type" , "Evangelist" , "zealous preacher" , "Bible reader" , "evangelical preacher" .)
