Home town's extremely welcoming - absolutely (2,4)
I believe the answer is:
in toto
'home town's extremely welcoming absolutely' is the definition.
I can't judge whether this defines the answer.
'home town's extremely welcoming absolutely' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'town' becomes 'toledo'.
'extremely' says to hollow out the word (remove centre letters).
'welcoming absolutely' becomes 'to' (I can't justify this - if you can you should believe this answer much more).
'toledo' with its middle removed is 'to'.
'in'+'to'+'to'='IN TOTO'
Can you help me to learn more?
(Other definitions for in toto that I've seen before include "Altogether, completely" , "Completely - entirely (Latin)" , "overall" , "In entirety" , "Wholly" .)
