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

'marriage' is the definition.
(I know that marriage can be written as union)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for union that I've seen before include "Coupling, merger" , "Fusion" , "Amalgam" , "Climbing plant" , "Result of joining" .)

I've seen this clue in The Irish News.
