Royal at home caught by invading newspapers (8)
I believe the answer is:
princess
'royal' is the definition.
(princess royal is a kind of royal)
'home caught by invading newspapers' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'caught by' becomes 'c' (cricket abbreviation. I am not sure about the 'by' bit.).
'invading' means one lot of letters goes inside another.
'newspapers' becomes 'press' (the press is the newspaper industry).
'in'+'c'='inc'
'inc' inserted inside 'press' is 'PRINCESS'.
'at' acts as a link.
Can you help me to learn more?
(Other definitions for princess that I've seen before include "A monarch's daughter" , "Royal title" , "Royal lady" , "Daughter of a sovereign" , "Sovereign's daughter" .)
