Information about Arab-Dutch plot (6)
I believe the answer is:
garden
'plot' is the definition.
(garden is a kind of plot)
'information about arab-dutch' is the wordplay.
'information' becomes 'gen' (gen is a kind of information).
'about' means one lot of letters goes inside another.
'arab' becomes 'ar' (abbreviation in Chambers).
'dutch' becomes 'd' (common abbreviation).
'ar'+'d'='ard'
'gen' going around 'ard' is 'GARDEN'.
(Other definitions for garden that I've seen before include "Cultivate a plot" , "Area for growing plants" , "Plant growing area" , "Ground adjoining house" , "Ranged (anag.)" .)
