Refuse to agree to project (5,3)
I believe the answer is:
stand out
'to project' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stand out that I've seen before include "Be conspicuous, or persist in demands" , "Be highly noticeable" , "Be particularly noticeable" , "Be conspicuous, or persist in demand" , "Be prominent or superior" .)
