Paper having no time for children (5)
I believe the answer is:
issue
'children' is the definition.
(thesaurus)
'paper having no time' is the wordplay.
'paper' becomes 'tissue' (tissue is a kind of paper).
'having no' indicates named letters should be taken away.
'time' becomes 't'.
'tissue' with 't' taken away is 'ISSUE'.
'for' is the link.
(Other definitions for issue that I've seen before include "Children, edition" , "Outcome - children" , "Matter for discussion" , "Topic; send out" , "important subject" .)
