A teen being disruptive around mother causing issue (7)
I believe the answer is:
emanate
'issue' is the definition.
(thesaurus)
'a teen being disruptive around mother' is the wordplay.
'being disruptive' is an anagram indicator.
'around' is an insertion indicator.
'mother' becomes 'ma' (ma is a kind of mother).
'a'+'teen'='ateen'
'ateen' with letters rearranged gives 'enate'.
'enate' enclosing 'ma' is 'EMANATE'.
'causing' is the link.
(Other definitions for emanate that I've seen before include "Come out (of source)" , "spring" , "Issue or originate from manatee" , "Rise" , "Come forth" .)
