The examples:
1. J’ai besoin d’aller faire les courses avant le dîner and
2. Je dois aller faire les courses avant dîner
I understand that in 1. the noun is used and in 2. the verb but in 2. could you also say
Je dois aller faire les courses avant le dîner ?
I’m asking because my mind translates 2. as - i need to go shopping before dining.
