Note freedom of movement initially denied the peerage (8)
I believe the answer is:
nobility
'the peerage' is the definition.
(I've seen this in another clue)
'note freedom of movement initially denied' is the wordplay.
'note' becomes 'n' (abbreviation).
'freedom of movement' becomes 'mobility' (I've seen this before).
'initially denied' means to remove the first letter (the word is denied its initial).
'mobility' with its initial letter removed is 'obility'.
'n'+'obility'='NOBILITY'
(Other definitions for nobility that I've seen before include "Privileged class holding hereditary titles" , "Aristocrats generally" , "excellence" , ""peers"" , "Peerage" .)
