Seedy old Romeo ejected from theatre in outskirts of Malvern (4-5)
I believe the answer is:
moth-eaten
'seedy old' is the definition.
'moth-eaten' can be an answer for 'old' (I've seen this before). I am unsure of the 'seedy' bit.
'romeo ejected from theatre in outskirts of malvern' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'ejected from' indicates named letters should be taken away.
'in' is an insertion indicator.
'outskirts of malvern' becomes 'mon' (I can't justify this - if you can you should give a lot more credence to this answer).
'theatre' with 'r' taken away is 'theate'.
'theate' put within 'mon' is 'MOTH-EATEN'.
Can you help me to learn more?
(Other definitions for moth-eaten that I've seen before include "Old and worn" , "Showing severe signs of wear and tear" , "Falling to bits" , "Damaged by insects" , "Tatty" .)
