Actually, the French stole our word design (keeping the same pronunciation, but of course with the French accent that exaggerates the long I vowel), which itself comes from the French word dessin meaning drawing. The French word design is used to refer to the general art, as in interior design. Some other meanings of the English word design would be translated differently, for example:
to develop/create -- concevoir, créer
a decorative pattern -- un motif
an idea -- une conception
