Home television advertisement placed within magazine? (5)
I believe the answer is:
inset
'advertisement placed within magazine?' is the definition.
I can't tell whether this defines the answer.
'home television' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'television' becomes 'set' (television set).
'in'+'set'='INSET'
Can you help me to learn more?
(Other definitions for inset that I've seen before include "Photographic cameo superimposed on to another print" , "Minor figure" , "Picture placed within another" , "one image within another" , "Part of picture" .)
