For example, something man-made might be found within vital structure, I see (9)
I believe the answer is:
inorganic
'for example something man-made might be' is the definition.
I can't judge whether this definition defines the answer.
'within vital structure i see' is the wordplay.
'within' becomes 'in'.
'vital structure' becomes 'organ' (I can't justify this - if you can you should believe this answer much more).
'see' becomes 'C' (the word for the letter, according to Chambers).
'in'+'organ'+'i'+'c'='INORGANIC'
'found' acts as a link.
Can you help me to learn more?
(Other definitions for inorganic that I've seen before include "Man-made" , "artificial" , "Not deriving from living matter" , "What can describe something alien to life" , "without carbon" .)
