What St. Andrew's has, that holds the spectators (5)
I believe the answer is:
stand
'what st' is the definition.
I can't judge whether this definition defines the answer.
'andrew's has that holds the spectators' is the wordplay.
'andrew' becomes 'St Andrew' (synonyms).
'has' is a charade indicator (letters next to each other).
'that holds the spectators' becomes 'and' (I can't justify this - if you can you should give a lot more credence to this answer).
'st'+'and'='STAND'
Can you help me to learn more?
(Other definitions for stand that I've seen before include "Get to one's feet" , "principled position" , "Decline to interfere when one should?" , "Raised platform; tolerate" , "Remain unaltered, tolerate" .)
