Learn Romanian: Duminică sunt acasă cu familia. - On Sunday I am at home with the family.

In Romanian, you don't need a preposition like "on" before days of the week to say something happens on that day. You just use the name of the day itself, so Duminică alone means "On Sunday".

Are days of the week usually capitalized in Romanian?

No, days of the week like luni (Monday) or duminică (Sunday) are normally written with lowercase letters. Duminică is only capitalized here because it is the first word of the sentence.

Who is the subject of sunt in this sentence?

The verb sunt can mean "I am" or "they are". Based on the context of being at home with the family, it means "I am" here. Romanian usually drops the pronoun eu (I) because the verb form already makes it clear who is doing the action.

Why is "at home" translated as one word, acasă?

Acasă is a special adverb that means "at home" all by itself. You don't need to use a separate preposition for "at" (like la) when talking about being at your own house.
