Sounds like a habit to get used to (8)
I believe the answer is:
accustom
'get used to' is the definition.
(I've seen this before)
'sounds like a habit' is the wordplay.
'sounds like' becomes 'ac' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a habit' becomes 'custom' (I've seen this before).
'ac'+'custom'='ACCUSTOM'
'to' is the link.
Can you help me to learn more?
(Other definitions for accustom that I've seen before include "Maybe reconcile" , "Familiarise" , "Make (someone) used to (something)" , "get one inured to" , "Adapt" .)
