The painting represents type of resistance patriot (8)
I believe the answer is:
portrait
'the painting' is the definition.
(portrait is a kind of painting)
'of resistance patriot' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'resistance' becomes 'r' (electronics abbreviation).
'r'+'patriot'='rpatriot'
'rpatriot' with letters rearranged gives 'PORTRAIT'.
'represents type' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for portrait that I've seen before include "Painting of a real person" , "Painted likeness of a person" , "Oil perhaps" , "(Person's) painting" , "Image of a person" .)
