Association giving the French the shivers? (6)
I believe the answer is:
league
'association' is the definition.
(I know that league is a type of association)
'giving the french the shivers?' is the wordplay.
'giving' means one lot of letters go next to another.
'the french' becomes 'le' ('the' in French).
'the shivers?' becomes 'ague' (I've seen this in another clue).
'le' next to 'ague' is 'LEAGUE'.
(Other definitions for league that I've seen before include "Coalition" , "Union - measure" , "some mileage?" , "Old distance measure of about three miles" , "'Nautical measure, about 3? miles (6)'" .)
