It's near breaking up and showing distress (2,5)
I believe the answer is:
in tears
'showing distress' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'it's near breaking up' is the wordplay.
'breaking up' indicates an anagram.
'its'+'near'='itsnear'
'itsnear' with letters rearranged gives 'IN TEARS'.
'and' is the link.
Can you help me to learn more?
(Other definitions for in tears that I've seen before include "Very unhappy" , "Crying" , "Maudlin" , "Weeping" , "sadly" .)
