Rent once due needs to be met (11)
I believe the answer is:
encountered
'to be met' is the definition.
(I've seen this in another clue)
'rent once due' is the wordplay.
'rent once due' can be anagrammed to 'ENCOUNTERED'.
Though, I'm not sure how this is indicated.
'needs' acts as a link.
Can you help me to learn more?
(Other definitions for encountered that I've seen before include "Met" , "Ran into" , "Came across" .)
