Bookmarks upside down in Vile Bodies (5)
I believe the answer is:
obeli
'bookmarks' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'upside down in vile bodies' is the wordplay.
'upside down' shows that the letters should be reversed in order.
'in' indicates a hidden word.
'ilebo' is hidden within 'vile bodies'.
'ilebo' backwards is 'OBELI'.
Can you help me to learn more?
(Other definitions for obeli that I've seen before include "Textual marks" , "Cross references" , "Marks on script" , "Dagger signs in printing" , "Printer's daggers" .)
