Clergyman has clay thrown out? Precisely! (10)
I believe the answer is:
accurately
'precisely' is the definition.
(thesaurus)
'clergyman has clay thrown out?' is the wordplay.
'clergyman has' becomes 'curate' (I can't justify this - if you can you should give a lot more credence to this answer).
'thrown' indicates an anagram.
'out?' means one lot of letters goes inside another.
'clay' is an anagram of 'acly'.
'curate' placed inside 'acly' is 'ACCURATELY'.
Can you help me to learn more?
(Other definitions for accurately that I've seen before include "in every detail" , "as result at 16A 25 24 [LARGE HADRON COLLIDER] is best recorded!" .)
