Andi Peters can be dull (10)
I believe the answer is:
pedestrian
'dull' is the definition.
(similar in meaning)
'andi peters can be' is the wordplay.
'can be' indicates an anagram.
'andi'+'peters'='andipeters'
'andipeters' with letters rearranged gives 'PEDESTRIAN'.
(Other definitions for pedestrian that I've seen before include "nothing much to write home about" , "lacking inspiration" , "Dull, uninspired" , "footman" , "lame" .)
