Train, etc., to work with one another (8)
I believe the answer is:
interact
'one another' is the definition.
I can't tell whether this defines the answer.
'train etc to work' is the wordplay.
'to work' indicates anagramming the letters (letters worked into a new order).
'train'+'etc'='trainetc'
'trainetc' anagrammed gives 'INTERACT'.
'with' is the link.
Can you help me to learn more?
(Other definitions for interact that I've seen before include "Combine" , "Be responsive to one another" , "Can't tire (anag)" , "Work with others" , "Work reciprocally" .)
