Supervision (or neglect) of deliveries, given stated location (9)
I believe the answer is:
oversight
'supervision' is the definition.
(I know that supervision can be written as oversight)
'deliveries given stated location' is the wordplay.
'deliveries' becomes 'over' (I've seen this before).
'given' is a charade indicator (letters next to each other).
'stated' shows a homophone (sound like).
'location' becomes 'site' (site is a kind of location).
'site' is a homophone of 'sight'.
'over'+'sight'='OVERSIGHT'
'or neglect of' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for oversight that I've seen before include "Failure to notice something" , "Supervisor's charged with this" , "Carelessness" , "Got shiver due to forgetfulness" , "A failure to notice, an omission" .)
