Spanish couple following king - union brings glory (5)
I believe the answer is:
kudos
'glory' is the definition.
(I've seen this before)
'spanish couple following king union' is the wordplay.
'spanish couple' becomes 'dos-' ('two' in Spanish).
'following' is a charade indicator (letters next to each other).
'king' becomes 'K' (abbreviation for king in chess).
'union' becomes 'U' (common abbreviation as in Trades Union Congress).
'k'+'u'='ku'
'dos' after 'ku' is 'KUDOS'.
'brings' acts as a link.
(Other definitions for kudos that I've seen before include "Informal honour of glory" , "Honour - cachet" , "Laudation" , "Distinction" , "Laurels" .)
