Teams up, arrives to collect bin (8)
I believe the answer is:
combines
'teams up' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot understand how they can define each other.
'arrives to collect bin' is the wordplay.
'arrives' becomes 'comes' ('come' can be a synonym of 'arrive').
'to collect' is an insertion indicator (inserted letters are collected by others).
'comes' placed around 'bin' is 'COMBINES'.
Can you help me to learn more?
(Other definitions for combines that I've seen before include "Put together" , "blends" , "Joins or merges to form a single unit" , "Joins or puts together" , "'Joins together, unites (8)'" .)
