Minor case involving filling? It'll bring tears to your eyes (6)
I believe the answer is:
weepie
'minor case involving filling? it'll' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'tears to your eyes' is the wordplay.
I cannot quite see how this works, but
'tears' could be 'weep' (I have seen 'Shed tears' mean 'weep' so perhaps 'tears' could also mean 'weep') and 'weep' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'bring' is the link.
Can you help me to learn more?
(Other definitions for weepie that I've seen before include "Something very sugary" , "tear-jerking film" , "could have you in tears" , "may be enjoyed in cinema" , "Love Story, among many" .)
