Errant fools disheartened about move (8)
I believe the answer is:
transfer
'move' is the definition.
(transfer is a kind of move)
'errant fools disheartened about' is the wordplay.
'disheartened' says to hollow out the word (remove centre letters).
'about' is an anagram indicator.
'fools' with its centre removed is 'fs'.
'errant'+'fs'='errantfs'
'errantfs' with letters rearranged gives 'TRANSFER'.
(Other definitions for transfer that I've seen before include "Removal" , "Change (from one thing to another)" , "Bring over" , "Give over!" , "Star fern (anag.)" .)
