Informed he left the aged
I believe the answer is:
told
'informed' is the definition.
(telling is a kind of informing)
'he left the aged' is the wordplay.
'left' suggests deleting specific letters.
'aged' becomes 'old' (similar in meaning).
'the' with 'he' taken out is 't'.
't'+'old'='TOLD'
(Other definitions for told that I've seen before include "Produced effect; related" , "Informed; narrated" , "Made an impact" , "Related (a story)" , "Said" .)
