Small page shed tears (4)
I believe the answer is:
weep
'shed tears' is the definition.
(thesaurus)
'small page' is the wordplay.
'small' becomes 'wee' ('wee' can be similar in meaning to 'small').
'page' becomes 'p'.
'wee'+'p'='WEEP'
(Other definitions for weep that I've seen before include "Display sorrow" , "Pee-pee" , "Express grief or sorrow" , "Cry, shed tears" , "Keen" .)
