Strange redesign I clear up (8)
I believe the answer is:
peculiar
'strange' is the definition.
(synonyms)
'redesign i clear up' is the wordplay.
'redesign' indicates anagramming the letters (I've seen 'redesigned' mean this).
'i'+'clear'+'up'='iclearup'
'iclearup' anagrammed gives 'PECULIAR'.
(Other definitions for peculiar that I've seen before include "Strange, I clear up" , "Extraordinary" , "Unusual" , "Belonging exclusively to, person or place" , "Strange or eccentric, quite odd" .)
