Figure anchored to construction (10)
I believe the answer is:
octahedron
'figure' is the definition.
(I have seen 'A figure' mean 'octahedron' so perhaps 'figure' could also mean 'octahedron')
'anchored to construction' is the wordplay.
'construction' indicates an anagram (answer constructed from certain letters).
'anchored'+'to'='anchoredto'
'anchoredto' with letters rearranged gives 'OCTAHEDRON'.
(Other definitions for octahedron that I've seen before include "A figure" , "solid" .)
