Picked up capital from Spain’s generosity (8)

I believe the answer is:

largesse

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

'generosity' is the definition.
(I know that largesse is a type of liberality)

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

Can you help me to learn more?

(Other definitions for largesse that I've seen before include "Les rages at the distribution of gifts" , "Generosity in gift-giving" , "Magnanimity, munificence" , "Generosity in bestowing gifts" , "charity" .)

I've seen this clue in The Sunday Times.
