Chart the Québécois growth, notably in Canada (5)
I believe the answer is:
maple
'growth notably in canada' is the definition.
I can't judge whether this defines the answer.
'chart the quebecois' is the wordplay.
'chart' becomes 'map' (synonyms).
'the quebecois' becomes 'le' (I can't explain this - if you can you should believe this answer much more).
'map'+'le'='MAPLE'
Can you help me to learn more?
(Other definitions for maple that I've seen before include "Cathedral city in Devon" , "Leaves on this" , "Tree whose leaf features on the flag of Canada" , "Tree: its leaf the Canadian emblem" , "Tree of the sycamore family" .)
