Missionary position in occasionally manlier embrace (7)
I believe the answer is:
apostle
'missionary' is the definition.
(I've seen this before)
'position in occasionally manlier embrace' is the wordplay.
'position in' becomes 'post' (post is a kind of position. I am not sure about the 'in' bit.).
'occasionally' means one should take alternating letters.
'embrace' means one lot of letters goes inside another.
The alternating letters of 'manlier' are 'ale'.
'post' placed into 'ale' is 'APOSTLE'.
Can you help me to learn more?
(Other definitions for apostle that I've seen before include "Religious messenger" , "Preacher perhaps" , "Peter, perhaps" , "Ale pots (anag)" , "James, perhaps" .)
