Largely avoid imparting a feeling of doubt (9)
I believe the answer is:
misgiving
'a feeling of doubt' is the definition.
(I've seen this before)
'largely avoid imparting' is the wordplay.
'largely' means to remove the last letter.
'avoid' becomes 'miss' (missing is a kind of avoiding).
'imparting' becomes 'giving' ('give' can be a synonym of 'impart').
'miss' with its last letter taken off is 'mis'.
'mis'+'giving'='MISGIVING'
(Other definitions for misgiving that I've seen before include "Feeling of doubt" , "Qualm, scruple" .)
