How royal corpse might fib in condition? (3,2,5)
I believe the answer is:
lie in state
'how royal corpse' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'fib in condition?' is the wordplay.
'fib' becomes 'lie' (a fib is a lie).
'condition?' becomes 'state' (the state something is in).
'lie'+'in'+'state'='LIE IN STATE'
'might' acts as a link.
Can you help me to learn more?
(Other definitions for lie in state that I've seen before include "rest in place of honour when dead" , "(Of body) be placed on public view before burial" , "late rulers?" , "(Of corpse) receive honour before burial" .)
