Went one by one out of the field (5)
I believe the answer is:
filed
'went one' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'one out of the field' is the wordplay.
'one out of' indicates anagramming the letters.
'field' is an anagram of 'FILED'.
'by' is the link.
Can you help me to learn more?
(Other definitions for filed that I've seen before include "arranged in a particular way" , "Noted" , "Placed in folder" , "Worked with a tool" , "Put away in a container for records" .)
