"Hugo eats all the sweets that he wants."

Translation: Hugo mange toutes les sucreries dont il a envie.

[HarishAbbe3]

Hugo mange toutes les sucreries qu'il veut. Is this fine?

[RichardHoma]

Yes. Duo accepted it when I entered that answer. You need 'dont' after 'avoir envie de', but 'que' is used with 'vouloir' because the verb doesn't use a preposition.

[Rosemary126626]

Thank you for that. I wondered when to use 'dont' as opposed to 'que'.

[Teo-GN]

I think so

[monterey3524]

Harish Abbee . On a previous post: dont=de que = of which. , so you may need de qu'il veut.

[MatthewB6]

Why not "Hugo mange toutes les sucreries dont il veut"?

[MatthewB6]

Replying to my own question 6 months later:

dont = de que

so il a envie de qqch becomes qqch dont il a envie

whereas il veut qqch becomes qqch qu'il veut

[Manas743231]

Why not?

Hugo mange toutes les sucreries dont il veut

[doublelingot]

Hugo mange toutes les sucreries dont qu'il veut.

[Hoal387727]

Thank you.

[pbt.hodges]

I think you need que when you use vouloir, dont replaces que when the verb takes a preposition of de, as in avoir envie de quelque chose

[Balla583491]

les bonbons dont il veut. what's wrong with this?

[RichardHoma]

I think 'bonbons' is too narrow...candy, rather than sweets in general.

[Denise407335]

As detailed above, if you use vouloir (veut), the relative pronoun that you use needs to be "que" not "dont" ie les bonbons qu'il veut
