Experiment with strikes in international meetings (4,7)
I believe the answer is:
test matches
'international meetings' is the definition.
The definition and answer can be both related to natural events as well as being plural nouns.
Maybe there's an association between them I don't understand?
'experiment with strikes' is the wordplay.
'experiment with' becomes 'test' (synonyms).
'strikes' becomes 'matches' (I can't justify this - if you can you should give a lot more credence to this answer).
'test'+'matches'='TEST MATCHES'
'in' is the link.
Can you help me to learn more?
(Other definitions for test matches that I've seen before include "competitions" , "Cricket fixtures" , "Give strikers a trial" , "important games" , "they can last for days" .)
