Manage to get a dry answer at home (6)
I believe the answer is:
attain
'manage to get' is the definition.
(I've seen this before)
'a dry answer at home' is the wordplay.
'dry' becomes 'tt' (abbreviation for teetotal).
'answer' becomes 'a' (abbreviation eg in Q and A).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'a'+'tt'+'a'+'in'='ATTAIN'
(Other definitions for attain that I've seen before include "Reach (a particular age)" , "Reach (a specified level)" , "Achieve or accomplish" , "Reach (age, size etc.)" , "Gain with effort" .)
