Smell alcohol on daughter, it's becoming routine (7)
I believe the answer is:
humdrum
'becoming routine' is the definition.
'humdrum' can be an answer for 'routine' (I've seen this before). I am not sure about the 'becoming' bit.
'smell alcohol on daughter' is the wordplay.
'smell' becomes 'hum' (something with a bad smell is 'humming').
'alcohol' becomes 'rum' (type of alcohol).
'on' is a charade indicator (letters next to each other).
'daughter' becomes 'd' (genealogical abbreviation).
'rum' put after 'd' is 'drum'.
'hum'+'drum'='HUMDRUM'
'it's' is the link.
Can you help me to learn more?
(Other definitions for humdrum that I've seen before include "Common place" , "Commonplace, dull" , "Routine and monotonous" , "Run of the mill" , "Everyday, tedious" .)
