Clamour from one imprisoned by beak? (5)
I believe the answer is:
noise
'clamour' is the definition.
(I've seen this before)
'one imprisoned by beak?' is the wordplay.
'one' becomes 'i' (Roman numeral).
'imprisoned by' means one lot of letters goes inside another.
'beak?' becomes 'nose' (beak is a kind of nose).
'i' placed into 'nose' is 'NOISE'.
'from' is the link.
(Other definitions for noise that I've seen before include "Loud or disturbing sound" , "Loud or unpleasant sound" , "Unpleasant sounds" , "Clamour" , "explosive report, for example" .)
