Engineers arrange delay getting transferred (7)
I believe the answer is:
relayed
'transferred' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'engineers arrange delay getting' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'arrange' indicates an anagram.
'getting' is an insertion indicator.
'delay' is an anagram of 'layed'.
're' placed within 'layed' is 'RELAYED'.
Can you help me to learn more?
(Other definitions for relayed that I've seen before include "Layered (anag.)" , "Received and passed on" , "Broadcast; passed on" , "Transmitted along" , "Passed along" .)
