Try British league and French cup (6)
I believe the answer is:
goblet
'cup' is the definition.
(I know that goblet is a type of cup)
'try british league and french' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'british' becomes 'b' (abbreviation e.g. in BBC).
'league' becomes 'l' (abbreviation).
'and french' becomes 'et' ('and' in French).
'go'+'b'+'l'+'et'='GOBLET'
(Other definitions for goblet that I've seen before include "Bowl-shaped drinking vessel" , "Ornate glass" , "Large drinking cup" , "Chalice" , "Large handleless drinking-cup" .)
