Somehow computerise nearly all valuable material (8,5)
I believe the answer is:
precious metal
'valuable material' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'somehow computerise nearly all' is the wordplay.
'somehow' is an anagram indicator.
'nearly all' becomes 'al'.
'computerise' is an anagram of 'preciousmet'.
'preciousmet'+'al'='PRECIOUS METAL'
Can you help me to learn more?
(Other definitions for precious metal that I've seen before include "Platinum, perhaps" , "Eg gold, silver or platinum" , "no lead!" , "gold, perhaps" .)
