To stare can make your eyes water! (5)
I believe the answer is:
tears
'your eyes water' is the definition.
I can't tell whether this definition defines the answer.
'to stare can make' is the wordplay.
'can make' is an anagram indicator.
'stare' with letters rearranged gives 'TEARS'.
Can you help me to learn more?
(Other definitions for tears that I've seen before include "See 12" , "Shed them and cry" , "Rents" , "damaging to paper" , "Rush special" .)
