Running just after I admitted to clanger? (7)
I believe the answer is:
ongoing
'running' is the definition.
('ongoing' can be a synonym of 'running')
'just after i admitted to clanger?' is the wordplay.
'just after' becomes 'on'.
'admitted to' means one lot of letters goes inside another.
'clanger?' becomes 'gong'.
'i' inserted into 'gong' is 'going'.
'on'+'going'='ONGOING'
(Other definitions for ongoing that I've seen before include "Currently in progress" , "Still in progress" , "Currently happening" , "Current" , "Not yet concluded" .)
