Am I less than friendly guy? (5)
I believe the answer is:
cable
'friendly guy?' is the definition.
'cable' can be an answer for 'guy?' (I've seen this in other clues). I am not sure about the 'friendly' bit.
'am i less than' is the wordplay.
'am' becomes 'came' (coming is a kind of being).
'i' becomes 'me'.
'less' indicates named letters should be taken away (less can mean minus).
'than' becomes 'ble' (I am not sure about this - if you are sure you should believe this answer much more).
'came' with 'me' taken out is 'ca'.
'ca'+'ble'='CABLE'
Can you help me to learn more?
(Other definitions for cable that I've seen before include "Hawser, wire" , "Satellite alternative?" , "Liberal Democrat" , "Thick wire; telegram" , "Telegraph" .)
