Cross and weary after the Spanish turned up (7)
I believe the answer is:
saltire
'cross' is the definition.
(saltire is a kind of cross)
'weary after the spanish turned up' is the wordplay.
'weary' becomes 'tire' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'the spanish' becomes 'las' ('the' in Spanish).
'turned up' says the letters should be written backwards.
'las' in reverse letter order is 'sal'.
'tire' after 'sal' is 'SALTIRE'.
'and' acts as a link.
(Other definitions for saltire that I've seen before include "The Scottish flag" , "X-shaped cross" , "flag - 8's? [SAINT ANDREW]" , "standard for Scots" , "Cross like St Andrew's" .)
