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

'for support' is the definition.
(prop up can mean to support)

'go quickly round the other end' is the wordplay.
'go quickly' becomes 'pop' (popping is a kind of going. I am not sure about the 'quickly' bit.).
'round' indicates putting letters inside.
'end' suggests the final letters.
The last letter of 'other' is 'r'.
'pop' placed around 'r' is 'PROP'.

Can you help me to learn more?

(Other definitions for prop that I've seen before include "Lean" , "player involved in scrum" , "Stay" , "Support; object used on stage" , "Hold (up), support" .)
