Scenario with hod redesigned? Probably not this shape (11)
I believe the answer is:
icosahedron
'probably not this shape' is the definition.
'icosahedron' can be an answer for 'shape' (icosahedron is a kind of shape). I am not certain of the remainder of the definition.
'scenario with hod redesigned?' is the wordplay.
'with' means one lot of letters go next to another.
'redesigned?' is an anagram indicator (I've seen 'redesigns' mean this).
'scenario'+'hod'='scenariohod'
'scenariohod' is an anagram of 'ICOSAHEDRON'.
Can you help me to learn more?
(Other definitions for icosahedron that I've seen before include "Figure" , "Twenty-faced solid" .)
