Shabby articles by English gallery (4)
I believe the answer is:
tate
'gallery' is the definition.
(Tate Modern, Tate Britain etc)
'shabby articles by english' is the wordplay.
'shabby articles' becomes 'tat' (a bunch of shabby items).
'by' says to put letters next to each other.
'english' becomes 'E' (abbreviation).
'tat'+'e'='TATE'
(Other definitions for tate that I've seen before include "Lord Sugar" , "Britain/Modern gallery" , "Maurice - - , cricketer 1895-1956" , "Art Gallery donor" , "Sugar merchant and art gallery philanthropist, founder, d. 1899" .)
