toasty

I'm a little stuck... Click here to teach me more about this clue!

'warm' is the definition.
(thesaurus)

'to a beastly home' is the wordplay.
'beastly home' becomes 'sty' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to'+'a'+'sty'='TOASTY'

Can you help me to learn more?

(Other definitions for toasty that I've seen before include "Pleasantly warm" , "Sandwich" , "snack" , "Cosily warm" , "Hot food" .)

I've seen this clue in The Telegraph.
