Make connection in detailed case (6)
I believe the answer is:
attach
'make connection' is the definition.
The definition and answer are not the same part of speech.
'detailed case' is the wordplay.
'detailed' means to remove the last letter (the tail of the word is removed).
'case' becomes 'attache' (attache is a kind of case).
'attache' with its final letter taken off is 'ATTACH'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for attach that I've seen before include "Fix to something else" , "Fasten, join, assign" , "Append, join" , "Add on to, couple" , "Document carriers" .)
