Silence is felt awkwardly (6)
I believe the answer is:
stifle
'silence' is the definition.
(I've seen this before)
'is felt awkwardly' is the wordplay.
'awkwardly' indicates an anagram.
'is'+'felt'='isfelt'
'isfelt' with letters rearranged gives 'STIFLE'.
(Other definitions for stifle that I've seen before include "Part of animal's leg" , "Suppress of choke" , "Asphyxiate - itself (anag)" , "Silence" , "Smother, suffocate" .)
