Lament verge I hit (6)
I believe the answer is:
grieve
'lament' is the definition.
(thesaurus)
'verge i hit' is the wordplay.
'hit' is an anagram indicator.
'verge'+'i'='vergei'
'vergei' is an anagram of 'GRIEVE'.
(Other definitions for grieve that I've seen before include "Feel intense sorrow at someone's death" , "Suffer great sorrow" , "Mourn, lament" , "Mourn, feel sorrow" , "Cause great distress to" .)
