Trouble including media presentation for thirty days (5)
I believe the answer is:
april
'thirty days' is the definition.
(I've seen this before)
'trouble including media presentation' is the wordplay.
'trouble' becomes 'ail' (synonyms).
'including' is an insertion indicator.
'media presentation' becomes 'pr' (I can't justify this - if you can you should give a lot more credence to this answer).
'ail' enclosing 'pr' is 'APRIL'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for april that I've seen before include "period of time" , "'All in an ... evening' (Katharine Tynan)" , "Spring month" , "Springtime rain" , "Month that's autumnal in Oz" .)
