About five, look to go without food (6)
I believe the answer is:
starve
'go without food' is the definition.
(I've seen this before)
'about five look' is the wordplay.
'about' is an insertion indicator.
'five' becomes 'v' (roman numeral).
'look' becomes 'stare' (stare is a kind of look**).
'v' going into 'stare' is 'STARVE'.
'to' acts as a link.
(Other definitions for starve that I've seen before include "Die of hunger" , "Suffer from want of food" , "Vaster (anag)" , "Suffer extreme hunger" , "Deprive of food" .)
