Connected little man was a fibber (6)
I believe the answer is:
allied
'connected' is the definition.
(I've seen this in another clue)
'little man was a fibber' is the wordplay.
'little man' becomes 'Al' (short for Alex, Alastair etc).
'was a fibber' becomes 'lied' (I can't explain this - if you can you should believe this answer much more).
'al'+'lied'='ALLIED'
Can you help me to learn more?
(Other definitions for allied that I've seen before include "United through treaty" , "Joined by treaty or agreement" , "in concert" , "Joined in friendship, treaty, etc" , "In league" .)
