Lopsided, wonky (5)
I believe the answer is:
askew
I believe this is a double definition.
'lopsided' is the first definition.
(synonyms)
'wonky' is the second definition.
(I know that wonky can be written as askew)
(Other definitions for askew that I've seen before include "Wonky" , "Out of line" , "Wakes (anag)" , "At an angle, 19 Down" , "Not straight or level, crooked" .)
