Concluding half of document entertains leading academic, as intended (5)
I believe the answer is:
meant
'as intended' is the definition.
(I've seen this before)
'concluding half of document entertains leading academic' is the wordplay.
'concluding' is a charade indicator (letters next to each other).
'half of' indicates taking half.
'document' becomes 'ms'.
'leading' indicates taking the first letters.
'academic' becomes 'ant' (I can't justify this - if you can you should believe this answer much more).
The first letter of 'entertains' is 'e'.
'ms' with half the letters taken is 'm'.
'm' next to 'e' is 'me'.
'me'+'ant'='MEANT'
Can you help me to learn more?
(Other definitions for meant that I've seen before include "intimated" , "Intentional" , "Denoted" , "no accident" , "Implied" .)
