Galactic ore distribution is unconditional (11)
I believe the answer is:
categorical
'unconditional' is the definition.
(synonyms)
'galactic ore distribution' is the wordplay.
'distribution' indicates an anagram.
'galactic'+'ore'='galacticore'
'galacticore' with letters rearranged gives 'CATEGORICAL'.
'is' is the link.
(Other definitions for categorical that I've seen before include "Unambiguously explicit" , "Unconditional" , "that's very clear" , "unqualified" .)
