I'm a little stuck... Click here to teach me more about this clue!

'supporters sort of excited about games taking part' is the definition.
I can't judge whether this defines the answer.

'supporters sort of excited about' is the wordplay.
'supporters' becomes 'est' (I am not sure about this - if you are sure you should believe this answer much more).
'excited' is an anagram indicator.
'about' indicates putting letters inside.
'sort'+'of'='sortof'
'sortof' is an anagram of 'footrs'.
'est' put within 'footrs' is 'FOOTRESTS'.

Can you help me to learn more?
