Now daughter comes in for a hot drink (5)
I believe the answer is:
toddy
'a hot drink' is the definition.
(I've seen this before)
'now daughter comes in' is the wordplay.
'now' becomes 'tody' (I can't justify this - if you can you should believe this answer much more).
'daughter' becomes 'd'.
'comes in' means one lot of letters goes inside another.
'tody' going around 'd' is 'TODDY'.
'for' is the link.
(Other definitions for toddy that I've seen before include "Drink made with spirits and hot water" , "Hot mixed drink" , "Mixture of spirits, sugar and hot water" , "Hot alcoholic drink" , "Palm tree sap" .)
