Had come to light when stranger is near (6)
I believe the answer is:
arisen
'had come to light' is the definition.
I can't tell whether this definition defines the answer.
'stranger is near' is the wordplay.
'stranger' is an anagram indicator.
'is'+'near'='isnear'
'isnear' is an anagram of 'ARISEN'.
'when' is the link.
Can you help me to learn more?
(Other definitions for arisen that I've seen before include "Sprung up" , "Up on the rocks" , "Gone up" , "It's appeared" , "(Having) occurred" .)
