Euro capital to back trendy grooves (8)
I believe the answer is:
rigatoni
'euro capital to back trendy grooves' is the definition.
I can't judge whether this definition defines the answer.
'euro capital to back trendy' is the wordplay.
'euro capital' becomes 'riga' (capital of Latvia. I am not sure about the 'euro' bit.).
'back' shows that the letters should be reversed in order.
'trendy' becomes 'in' ('in' can mean fashionable).
'in' in reverse letter order is 'ni'.
'riga'+'to'+'ni'='RIGATONI'
Can you help me to learn more?
(Other definitions for rigatoni that I've seen before include "Pasta; at origin (anag.)" , "Pasta - I got rain (anag)" , "Short, ribbed, tubular pasta" , "Short fluted tubes of pasta" , "Foodstuff" .)
