Minister, one having arrived at pulpit, initially? (8)
I believe the answer is:
preacher
'minister' is the definition.
(someone who preaches)
'one having arrived at pulpit initially?' is the wordplay.
'one having arrived' becomes 'reacher' (someone who has reached a destination).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'initially?' suggests taking the first letters (I've seen 'initially' mean this).
The initial letter of 'pulpit' is 'p'.
'reacher' after 'p' is 'PREACHER'.
(Other definitions for preacher that I've seen before include "Religious minister" , "One spreading religious message" , "One giving a sermon" , "Someone spreading a gospel" , "Minister, clergyman" .)
