In the habit of having you, me and Edward as well? Almost! (4,2)
I believe the answer is:
used to
'in the habit of' is the definition.
(someone used to something is in the habit of it)
'me and edward as well? almost' is the wordplay.
'me' becomes 'us' ('us' can mean 'me' in some dialects).
'and' is a charade indicator (letters next to each other).
'edward' becomes 'Ed' (short for Edward).
'as well?' becomes 'too' (both can mean 'also').
'almost' means to remove the last letter (most of the word but not all of it).
'too' with its final letter taken away is 'to'.
'us'+'ed'+'to'='USED TO'
'having you' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for used to that I've seen before include "Familiar with" , "Accustomed or inured" , "Was in the habit" , "Not unfamiliar with" , "Did at times in the past" .)
