Spanish article, just outside, set on fire again (7)
I believe the answer is:
relight
'set on fire again' is the definition.
('light' is an answer for 'set on fire' so perhaps 'relight' is OK for 'set on fire again')
'spanish article just outside' is the wordplay.
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'just' becomes 'right' (associated in meaning).
'outside' indicates putting letters inside.
'el' put within 'right' is 'RELIGHT'.
(Other definitions for relight that I've seen before include "fire again?" , "Ignite again" , "The girl (anag)" , "Rekindle" , "set off again" .)
