The fear somehow gets some down (7)
I believe the answer is:
feather
'some down' is the definition.
(thesaurus)
'the fear somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'the'+'fear'='thefear'
'thefear' with letters rearranged gives 'FEATHER'.
'gets' acts as a link.
(Other definitions for feather that I've seen before include "Quill" , "Free hat (anag)" , "Part of a bird's plumage" , "manipulate oar" , "Part of covering of bird" .)
