Make standard inside Scandinavian country (9)
I believe the answer is:
normalise
'make standard' is the definition.
Both the definition and answer are verbs in their base form.
I also know that 'standard' relates to this answer.
'inside scandinavian country' is the wordplay.
'inside' means one lot of letters goes inside another.
'scandinavian' becomes 'Norse' (Norse can mean relating to ancient Scandinavia).
'country' becomes 'mali' (Mali is an example).
'norse' enclosing 'mali' is 'NORMALISE'.
Can you help me to learn more?
(Other definitions for normalise that I've seen before include "Make usual" , "become commonplace" , "Standardise" , "bring within limits" .)
