Hostility if elder nuns sin all over the place (14)

I believe the answer is:

unfriendliness

'hostility' is the definition.
(I've seen this before)

'if elder nuns sin all over the place' is the wordplay.
'all over the place' indicates an anagram.
'if'+'elder'+'nuns'+'sin'='ifeldernunssin'
'ifeldernunssin' anagrammed gives 'UNFRIENDLINESS'.

(Another definition for unfriendliness that I've seen is " Personal hostility".)

I've seen this clue in The Telegraph.
