Material for modelling credit in Spain (10)
I believe the answer is:
plasticine
'material' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'modelling credit in spain' is the wordplay.
'modelling credit' becomes 'plastic' (I can't justify this - if you can you should believe this answer much more).
'spain' becomes 'e' (abbreviation for Espana).
'plastic'+'in'+'e'='PLASTICINE'
'for' is the link.
Can you help me to learn more?
(Other definitions for plasticine that I've seen before include "substance used by modellers" , "Modelling clay" .)
