Questions & Answers about Ona radi sporije, jer je umorna.

Why is ona used here? Can Serbian leave it out?

Yes. Serbian often drops subject pronouns when the verb already shows who the subject is.

So:

• Ona radi sporije, jer je umorna.
• Radi sporije, jer je umorna.

Both are correct.

Using ona can add emphasis, contrast, or clarity. For example, it may mean she works more slowly, not someone else.

What does radi mean exactly here?

Radi is the 3rd person singular present tense of raditi.

It can mean:

• she works
• she is working
• sometimes it works / it is functioning, depending on context

In this sentence, it means she works / she is working more slowly.

Why is it sporije and not sporo?

Because sporije is the comparative adverb form, meaning more slowly or slower in English.

Compare:

• sporo = slowly
• sporije = more slowly

So:

• Ona radi sporo. = She works slowly.
• Ona radi sporije. = She works more slowly.

English often uses slower where Serbian uses the comparative adverb .
