The position of délicieux in relation to the noun it is describing.

Question

Why is "délicieux" placed before the noun in  A great weekend and A Thanksgiving gift, "un délicieux repas" but after the noun in A romantic trip to Paris "des vins délicieux"

Accepted Answer

Délicieux can be put before or after the noun. The more common place is after the noun. Putting it before the noun is a bit more refined and a slightly higher register.

Answer

Bonjour Kay,
To supplement Chris's excellent answer, here is a list of French adjectives (non exhaustive) which can be placed before or after the noun: adorable, délicieux, étonnant, extraordinaire, horrible, fantastique, magnifique, superbe, stupide, splendide.
Also, placing such an adjective before the noun helps highlight the feeling / opinion expressed.
I hope this is helpful.
Bonne journée !
