"Vuole degli occhiali rossi."

Translation: She wants some red glasses.

When did 'degli' become 'some'?

[Danger-mouse]

conjunction of "di" (of) and "gli" (the). It's always used for nouns that have the article "gli"!

[xyphax]

While you are correct, what you are speaking of is when 'di' is used as a prepositional article. Here I believe 'di' is used as a partitive article. See this link:

[elainekirk]

why doesn't DL ever use the formal you and even marks it wrong. What do native Italians do? Can you use the informal you with anyone?

[Pier_Golfoz]

if DL doesn't accept "formal tu", you can report

Formal "tu" (Lei) is used if you are talking with an unknown person older than you.

EDIT @Bar292933
"Lei" is used as formal "tu" for both genders

[Bar292933]

must that old person be a female or could it be also a male one, in case "Lei" is used?

[gioglifx]

Lei (with capital L) is the "tu" form for both he and she. "lei" is she.

• io = I
• tu = you (informal for both male/female)
• Lei = you (formal for both male/female) lui = he lei = she Etc..

Why are we using "some" here?
There is no use of "some" actually,we can simply say glasses but not "some glasses".It sounds odd here.

[Pier_Golfoz]

"degli"(some), here, is a partitive article
it can mean "one(1) or more glasses"

(1) usually asking for a pair of glasses is more correct to say "vorrei un paio di occhiali" (but "degli" is grammatically correct too)

[carinofranco]

red eyeglasses is marked wrong. I reported it.

[donatoadc]

Who does he think he is Elton John?

[corbin_dunn]

Why can't this also be "You want some red glasses"?

[BlancheDB]

You're right. It can be the formal "you". I reported it, and told them it will confuse people later on if they say it's wrong. I don't know if they'll fix it or not, though. Hope so. I think it's strange that they don't teach the formal you from the beginning. Do they want us all to seem rude and overly familiar when talking to people?

[mangoHero1]

Formal you is rarely ever used outside of its own topic.

[Russ_Man_German]

This is a weird translation. "Some" red glasses?

[GregDAugustine]

I don't think this phrase would be much used in American English. We would typically say "He wants THE red eyeglasses", not "SOME".

[jannmill]

I also thought vuole was you because i remember a native speaker asking (me) Che cosa vuole fare? Lol i didn't notice that DL never uses the formal. Di they use it in Rome? That's where I'm going. Is this program going to make me sound disrespectful when i try speaking Italian there?

[Xenos2]

And still, noone has yet wondered what that phrase could possibly mean in terms of sense?
And why DL make so funny phrases from time to time?

[StefanMija]

Why is he nor she????

[Jones-Jim]

She wants some red specs is marked as wrong even though the drop down hint for 'occhiali' mentions 'specs'
