Blessed person rested outside home (5)
I believe the answer is:
saint
'blessed person' is the definition.
'saint' can be an answer for 'person' (saint is a kind of person). I am unsure of the 'blessed' bit.
'rested outside home' is the wordplay.
'rested' becomes 'sat' (to sit is to rest).
'outside' is an insertion indicator.
'home' becomes 'in' (to be in is to be (at) home).
'sat' enclosing 'in' is 'SAINT'.
Can you help me to learn more?
(Other definitions for saint that I've seen before include "Very virtuous person" , "See 6" , "eg Paul, Peter, Valentine" , "Holy man" , "eg John, Paul or George" .)
