Prejudiced as I moved in garden area (6)
I believe the answer is:
biased
'prejudiced' is the definition.
(biasing is a kind of prejudicing)
'as i moved in garden area' is the wordplay.
'moved' indicates anagramming the letters.
'in' indicates putting letters inside.
'garden area' becomes 'bed' (as in a flower bed).
'as'+'i'='asi'
'asi' with letters rearranged gives 'ias'.
'ias' put within 'bed' is 'BIASED'.
(Other definitions for biased that I've seen before include "Favouring one person or side over another" , "Prejudiced or influenced in favour or against" , "not fair" , "Having favourite" , "Influenced unfairly" .)
