Woeful cry (4)
I believe the answer is:
alas
'woeful cry' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alas that I've seen before include "-- and alack!" , "'- Poor Yorick' (Hamlet)" , "Expression of grief or misfortune" , "Expression of grief/pity" , "Sadly, unfortunately" .)
