Charitable people overlooking new openings (5)
I believe the answer is:
doors
'openings' is the definition.
(I've seen this before)
'charitable people overlooking new' is the wordplay.
'charitable people' becomes 'donors' (people who donate).
'overlooking' is a deletion indicator.
'new' becomes 'n'.
'donors' with 'n' taken away is 'DOORS'.
(Other definitions for doors that I've seen before include "Portals" , "Swinging or sliding barriers" , "Entrance barriers" , "Openings" , "Barriers to entrances" .)
