Point out only that it's man-made (5)
I believe the answer is:
nylon
'point' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'only that it's man-made' is the wordplay.
'that it's man' becomes 'N' (knight, a man in chess).
'made' indicates anagramming the letters.
'only'+'n'='onlyn'
'onlyn' is an anagram of 'NYLON'.
'out' is the link.
Can you help me to learn more?
(Other definitions for nylon that I've seen before include "Artific ial (stocking) material" , "Polyamide" , "where ladder can appear?" , "Fibrous material" , "Hose" .)
