Meaning of l'aspect défi

Question

In the sentence, "De plus, l'aspect défi de cette initiative permet de déstigmatiser la non-consommation d'alcool...", I don't understand 'l'aspect défi'.  In my dictionary, aspect and défi are both nouns, aspect and challenge respectively.  Can you first translate and then explain?  Thanks.

Accepted Answer

I think this would also be translated as a noun in English - "the challenge aspect". The point is not that it is "challenging", i.e. more difficult, but that it is framed as a challenge, which makes it more  attractive to get involved in.

Answer

De plus, l'aspect défi de cette initiative permet de déstigmatiser la non-consommation d'alcool... -- Furthermore, the challenging aspect of this initiative helps destigmatize consumption of no alcoholIn French, it's not uncommon to use nouns sequentially without an intervening preposition, especially when one noun is modifying or describing the other. In this case, "défi" is used to modify or describe "aspect." So, "aspect défi" together conveys the idea of a "challenge aspec"t. This is a grammatical construct often used in French to express complex ideas concisely.
