Anagram aligns with edges of eligible fodder (8)
I believe the answer is:
ensilage
'fodder' is the definition.
(I've seen this in another clue)
'anagram aligns with edges of eligible' is the wordplay.
'anagram' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'edges of' says to hollow out the word (remove centre letters).
'eligible' with its centre removed is 'ee'.
'aligns' put after 'ee' is 'eealigns'.
'eealigns' anagrammed gives 'ENSILAGE'.
(Other definitions for ensilage that I've seen before include "fermentation" , "Making fodder" , "Store fodder in silos" .)
