"The capital of UAE is Riyadh", Miles snarled, leaving close to apoplexy (6)

I believe the answer is:

dirham

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

'the capital of uae' is the definition.
(I know that United Arab Emirates\\u0027 currency is the dirham)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for dirham that I've seen before include "change from Casablanca!" , "Libyan CURRENCY" , "Moroccan currency" , "bread" , "money in Africa" .)

I've seen this clue in The Independent.
