Fire up again at conservative side repressing the Spanish (7)
I believe the answer is:
relight
'fire up again' is the definition.
('light' can be a synonym for 'fire up' so perhaps 'relight' is OK for 'fire up again')
'conservative side repressing the spanish' is the wordplay.
'conservative side' becomes 'right' (I am not sure about the 'conservative' bit.).
'repressing' is an insertion indicator.
'the spanish' becomes 'el' ('the' in Spanish).
'right' placed around 'el' is 'RELIGHT'.
'at' acts as a link.
Can you help me to learn more?
(Other definitions for relight that I've seen before include "Ignite again" , "Rekindle" , "get going over" , "The girl (anag)" , "fire again?" .)
