"Cei doi cumnați vorbesc cu mătușa bătrână."

Translation: The two brothers-in-law speak with the old aunt.

Could someone explain the use of "cei" as a definite article? Seems to happen when there is a number specification on the noun, but I haven't seen it explained here.

I'd like to know this too!

I've been attempting to read news articles in Romanian, and it literally just means 'the'. I think the '-ul' rule we learned earlier on is just used on nouns if I'm not mistaken. I'd like to know the correct answer though

I asked that question 3 months ago, I've learned many more things now. In this sentence it really is just a definite article. As far as I know they don't really put definite article -ul on numbers, so when there is a number such as here they use this way to show the definite article.

They sometimes use it to just accent on an adjective, though I am not sure if there is any other reason, in phrases like "calculator cel nou" - "The new computer".

And if it is used alone it means just "the one(s)":
"Cei pe care îi iubesc" - "The ones I love"

What's the difference between 'bătrână' and 'vechi', and when do you use one instead of the other?

[Enchom]

Disclaimer: I am not a native speaker just studying it, so I don't know how accurate my answer is.

"bătrân" is used for people. "bătrână" is the feminine form of the adjective.

"vechi" is used for objects.

I am not sure if "bătrân" is only for people or for all living things. That is, I am not sure how you would refer to an animal, but I'd guess "bătrân".

Makes sense, thanks
