Go without food — tears flowing about five? (6)
I believe the answer is:
starve
'go without food' is the definition.
(I've seen this before)
'tears flowing about five?' is the wordplay.
'flowing' is an anagram indicator.
'about' indicates putting letters inside.
'five?' becomes 'v' ('V' can be a synonym of 'five').
'tears' with letters rearranged gives 'stare'.
'stare' going around 'v' is 'STARVE'.
(Other definitions for starve that I've seen before include "Fail to take in" , "Eat nothing" , "Suffer extreme hunger" , "Suffer from want of food" , "Vaster (anag)" .)
