Article behind the damaged iPhone box on a fear of foreigners (10)
I believe the answer is:
xenophobia
'a fear of foreigners' is the definition.
(I've seen this before)
'article behind the damaged iphone box' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'behind' is a charade indicator (letters next to each other).
'the damaged' indicates anagramming the letters.
'iphone'+'box'='iphonebox'
'iphonebox' is an anagram of 'xenophobi'.
'a' after 'xenophobi' is 'XENOPHOBIA'.
'on' is the link.
(Other definitions for xenophobia that I've seen before include "Hatred of the foreign" , "Fear or dislike of foreigners" , "hating aliens" , "Excessive fear of foreigners" , "fear, stranger related" .)
