Topple series of deliveries worth recycling (9)
I believe the answer is:
overthrow
'topple series' is the definition.
'overthrow' can be an answer for 'topple' (thesaurus). I'm not certain of the 'series' bit.
'deliveries worth recycling' is the wordplay.
'deliveries' becomes 'over' (I've seen this before).
'recycling' indicates an anagram.
'worth' anagrammed gives 'throw'.
'over'+'throw'='OVERTHROW'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for overthrow that I've seen before include "Error on cricket field - defeat" , "Bring down rulers" , "Remove forcibly from power" , "Dethrone, cause downfall of" , "Bring down a ruler" .)
