Conduced round home, given internal protection (5)
I believe the answer is:
lined
'given internal protection' is the definition.
(to cover something's insides with material)
'conduced round home' is the wordplay.
'conduced' becomes 'led' (conduce can mean to cause or lead to).
'round' indicates putting letters inside.
'home' becomes 'in' ('he's home' can mean 'he's in').
'led' placed around 'in' is 'LINED'.
(Other definitions for lined that I've seen before include "What ruler did" , "given protection" , "Inlaid" , "Went along with" , "Wrinkled or with layer of material on inside" .)
