Source of pride put on a Spanish beach (5)
I believe the answer is:
playa
'spanish beach' is the definition.
(I've seen this in another clue)
'source of pride put on a' is the wordplay.
'source of' suggests taking the first letters (the start - or source - of the word).
'put' becomes 'lay' (as in laying or putting something down).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
The first letter of 'pride' is 'p'.
'p'+'lay'+'a'='PLAYA'
(Other definitions for playa that I've seen before include "Expanse of dry land" , "Spanish beach" , "lake after rainfall" , "piece of land liable to flood" , "bed in Spain" .)
