Reputation inherent in the Spanish paint (6)
I believe the answer is:
enamel
'paint' is the definition.
(I know that enamel is a type of paint)
'reputation inherent in the spanish' is the wordplay.
I cannot quite see how this works, but
'reputation' could be 'name' (someone's good name is their reputation) and 'name' is found in the answer.
'the spanish' could be 'el' ('the' in Spanish) and 'el' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for enamel that I've seen before include "Crown Protector?" , "Glassy substance" , "Nail polish" , "Smooth hard paint" , "canine protection?" .)
