Disagreeable din carrying over miles (7)
I believe the answer is:
noisome
'disagreeable' is the definition.
(I've seen this before)
'din carrying over miles' is the wordplay.
'din' becomes 'noise' (a din is a noisy disturbance).
'carrying' means one lot of letters goes inside another.
'over' becomes 'o' (cricket abbreviation).
'miles' becomes 'm' (common abbreviation).
'o'+'m'='om'
'noise' placed around 'om' is 'NOISOME'.
(Other definitions for noisome that I've seen before include "Moonies (anag.)" , "Smelling bad" , "Offensive, noxious" , "Offensively malodorous" , "noxious smells" .)
