At home glued to, disposed to have a drink (7)
I believe the answer is:
indulge
'a drink' is the definition.
(thesaurus)
'at home glued to disposed' is the wordplay.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'to disposed' is an anagram indicator.
'glued' is an anagram of 'dulge'.
'in'+'dulge'='INDULGE'
'to have' acts as a link.
(Other definitions for indulge that I've seen before include "Partake" , "Yield to the wishes of" , "pet" , "Allow person to have what he/she wishes" , "Cater to, pamper" .)
