Blend in on the way round motorway with the French (9)
I believe the answer is:
commingle
'blend' is the definition.
(commingling is a kind of blending)
'in on the way round motorway with the french' is the wordplay.
'in' indicates putting letters inside.
'on the way' becomes 'coming' ('coming' can be a synonym of 'on the way').
'round motorway' becomes 'm' (I am not sure about the 'round' bit.**).
'with' says to put letters next to each other.
'the french' becomes 'le'.
'coming' enclosing 'm' is 'comming'.
'comming'+'le'='COMMINGLE'
Can you help me to learn more?
(Another definition for commingle that I've seen is " Mix, blend".)
