Search about to stop is creating problems (9)
I believe the answer is:
questions
'problems' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'search about to stop is' is the wordplay.
'search' becomes 'quest' (quest is a kind of search).
'about to' becomes 'on' (I can't justify this - if you can you should give a lot more credence to this answer).
'stop' is an insertion indicator (stopping can mean blocking a gap).
'on' placed into 'is' is 'ions'.
'quest'+'ions'='QUESTIONS'
'creating' acts as a link.
Can you help me to learn more?
(Other definitions for questions that I've seen before include "posers?" , "See 8" , "Interrogates" , "pumps" .)
