Incorporate dome by reconstruction (6)
I believe the answer is:
embody
'incorporate' is the definition.
(both can mean to give physical form)
'dome by reconstruction' is the wordplay.
'reconstruction' indicates an anagram (I've seen 'reconstructions' mean this).
'dome'+'by'='domeby'
'domeby' with letters rearranged gives 'EMBODY'.
(Other definitions for embody that I've seen before include "Express ideas in visible or tangible form" , "Give a concrete form to" , "Give form to (idea)" , "Give solid form to" , "Epitomise" .)
