I believe the answer is:

suspend

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

'hold up' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for suspend that I've seen before include "Adjourn" , "Hold up or dangle" , "Hang, defer" , "Hang - discontinue" , "Stay" .)

I've seen this clue in The Telegraph.
