Questions & Answers about Я работаю допоздна.

What does допоздна mean in this sentence?

Допоздна is an adverb meaning “until late,” “late into the night,” or simply “late.”

Why is it written as one word допоздна instead of two words до поздно?

Допоздна is a single fused adverb formed historically from до + поздно. It’s not split in modern Russian.

What part of speech is допоздна?

It’s an adverb modifying the verb работаю, telling you how late the action continues.

Why is the verb работаю in the present tense if the action happens late at night?

Here the present tense expresses a habitual or regular action: “I (usually) work late.” If you wanted to say you worked late tonight (completed action), you’d use a perfective past: Я поработал(а) допоздна.

Can you omit the pronoun я in Я работаю допоздна?

Yes. Russian often drops the subject pronoun because the verb ending -ю already indicates the first person singular:
Работаю допоздна.
