Attempt meeting of bridge opponents, for example (5)
I believe the answer is:
essay
'attempt' is the definition.
(essay can mean to try or attempt something)
'meeting of bridge opponents for example' is the wordplay.
'meeting of bridge opponents' becomes 'ES' (East and South are opponents in bridge).
'for example' becomes 'say' ('say' can be used to introduce an example).
'es'+'say'='ESSAY'
(Other definitions for essay that I've seen before include "Analytic or interpretive literary composition (5_" , "Test" , "Try; short written work" , "What may be written in exam" , "Try; dissertation" .)
