Tries to correct extreme spin (11)
I believe the answer is:
experiments
'tries' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'correct extreme spin' is the wordplay.
'correct' indicates anagramming the letters.
'extreme'+'spin'='extremespin'
'extremespin' is an anagram of 'EXPERIMENTS'.
'to' acts as a link.
Can you help me to learn more?
(Another definition for experiments that I've seen is " Trials".)
