Enormity from rogue seen stopping loving gestures (8)
I believe the answer is:
hugeness
'enormity' is the definition.
(thesaurus)
'rogue seen stopping loving gestures' is the wordplay.
'rogue' indicates an anagram (letters go rogue).
'stopping' is an insertion indicator (stopping can mean blocking a gap).
'loving gestures' becomes 'hugs' (I can't justify this - if you can you should give a lot more credence to this answer).
'seen' is an anagram of 'enes'.
'enes' put within 'hugs' is 'HUGENESS'.
'from' is the link.
Can you help me to learn more?
(Another definition for hugeness that I've seen is " Vastness".)
