Go near nuts or fruit (6)
I believe the answer is:
orange
'fruit' is the definition.
(orange is a kind of fruit)
'go near nuts' is the wordplay.
'nuts' is an anagram indicator (nuts can mean crazy).
'go'+'near'='gonear'
'gonear' anagrammed gives 'ORANGE'.
'or' is the link.
(Other definitions for orange that I've seen before include "Name of reigning house of the Netherlands" , "Fruit - part of the spectrum" , "Round fruit (6)" , "Go earn the fruit" , "Belisha beacon colour" .)
