Second shopping area is modest (5)
I believe the answer is:
small
'modest' is the definition.
(thesaurus)
'second shopping area' is the wordplay.
'second' becomes 's' (common abbreviation).
'shopping area' becomes 'mall' (I've seen this before).
's'+'mall'='SMALL'
'is' is the link.
(Other definitions for small that I've seen before include "Petite" , "Minute" , "Insignificant; young" , "Diminutive" , "Of little size" .)
