Salesperson with Spanish article will revolt (5)
I believe the answer is:
repel
'revolt' is the definition.
(I know that revolt can be written as repel)
'salesperson with spanish article' is the wordplay.
'salesperson' becomes 'rep' (sales rep).
'with' means one lot of letters go next to another.
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'rep'+'el'='REPEL'
'will' acts as a link.
(Other definitions for repel that I've seen before include "Turn away" , "may turn your stomach" , "Drive back, rebuff" , "Drive back like leper" , "Drive away like leper" .)
