Reserve about to get second European piece of furniture (8)
I believe the answer is:
bookcase
'furniture' is the definition.
(I know that Bookcase is a furniture)
'reserve about to get second european piece' is the wordplay.
'reserve' becomes 'book' (to book something is to reserve it).
'about' is a reversal indicator.
'to get second' becomes 'e' (and letter of 'get').
'european piece' becomes 'sac' (sac is a kind of piece. I am not sure about the 'european' bit.).
'e'+'sac'='esac'
'esac' in reverse letter order is 'case'.
'book'+'case'='BOOKCASE'
'of' is the link.
Can you help me to learn more?
(Other definitions for bookcase that I've seen before include "rack" , "Article of furniture" , "Library furniture" , "written works here" , "It will be shelved" .)
