Neglect; look out upon (8)
I believe the answer is:
overlook
I believe this clue is a double definition.
'neglect' is the first definition.
(synonyms)
'look out upon' is the second definition.
(thesaurus)
(Other definitions for overlook that I've seen before include "Miss; forgive" , "Fail to observe or decide to ignore" , "excuse" , "Ignore a fault or have a view from above" , "Ignore or fail to notice" .)
