Agreement of adjectives

Question

Une solution gagnant-gagnant. Gagnant- gagnant . C’est parce-ce qu’il y a deux mots gagnants qui suivent le mot solution?Si on a une solution gagnante? Ici on doit faire accorder gagnant?

Hi Catriona, 
This reminded me of the a book by Stephen Covey :
'Les sept habitudes de ceux qui réalisent tout ce qu'ils entreprennent'
a lengthy translation of the American,  'Seven habits of highly effective people'!
And this is habit #4 :
Pensez gagant/gagnant = Think win/win 
and not -
gagnant/perdant =win/lose
perdant/gagnant = lose/win
perdant/perdant = lose/lose
etc.
These are set expressions and remain invariable.
But this book is a great read, available in French, and it will change the way you look at life...

Je pense que "gagnant-gagnant" est une expression invariable. Mais "une solution gagnante" serait certainement également correcte.

Chris Wirt · Answer

Yes, gagnant-gagnant ("win-win") is invariable, yet the adjective gagnant used by itself would change according to number and gender of the noun it refers to.
