Gledam strašan film.

Gledam means I am watching or I watch, depending on context.

It is:

• the 1st person singular form
• of the verb gledati (to watch / to look at)
• in the present tense

So gledam by itself means I watch / I am watching.

In Serbian, the present tense often covers both:

• I watch
• I am watching

The wider context tells you which English translation fits best.

Serbian does not use articles like English a and the.

So:

• film can mean a film or the film
• strašan film can mean a terrible/amazing film or the terrible/amazing film

You figure out whether it is a or the from context.

That is very normal in Serbian, and learners need to get used to nouns appearing without articles.

Because film here is the direct object of the verb gledam, and with this verb the direct object usually goes in the accusative case.

For the noun film, the accusative singular is the same as the nominative singular:

• nominative: film
• accusative: film

So the form does not visibly change.

This happens with many masculine inanimate nouns in Serbian: nominative and accusative singular look the same.

The adjective strašan has to agree with the noun film.

Film is:

• masculine
• singular
• here in the accusative
• and it is inanimate

For masculine inanimate nouns in the accusative singular, the adjective form is the same as the nominative masculine singular:

• strašan film

So the adjective matches the noun in:

• gender
• number
• case

That agreement is a basic feature of Serbian grammar.

Not always. Strašan can be tricky because it can mean different things depending on tone and context.

Common meanings include:

• terrible
• awful
• frightening
• sometimes amazing, incredible, or intense in informal speech

So Gledam strašan film could mean:

• I’m watching a terrible film
• I’m watching a scary film
• sometimes even I’m watching an amazing film, depending on context and speaker intention

If the meaning has already been given to the learner, that context decides which sense is intended.

No, Serbian word order is fairly flexible.

The neutral order here is:

• Gledam strašan film.

But other orders are possible, for example:

• Strašan film gledam.
• Film gledam.
• Gledam film.

Changing the order usually changes the focus or emphasis, not the core meaning.

For example:

• Gledam strašan film = neutral statement
• Strašan film gledam = emphasis on what kind of film
• Film gledam = emphasis on film as the thing being watched

Yes, you could.

Serbian usually drops personal pronouns when they are not needed, because the verb ending already shows the person:

• gledam = I watch / I am watching

So:

• Gledam strašan film is the normal, natural version
• Ja gledam strašan film is also correct, but ja adds emphasis

Using ja may suggest something like:

• I’m the one watching a terrible film
• I am watching it, not someone else

Gledati is an imperfective verb.

That matters because imperfective verbs are used for:

• ongoing actions
• repeated actions
• general habits

So Gledam strašan film naturally means something like:

• I’m watching a terrible film
• I watch terrible films (in the right context, though this exact sentence more naturally suggests a current action)

If you wanted a perfective idea, Serbian would normally use a different verb form or a different verb altogether, depending on what exactly you want to express.

A rough pronunciation guide for English speakers is:

• Gledam ≈ GLEH-dam
• strašan ≈ STRAH-shan
• film ≈ film

A few notes:

• g is always a hard g, like in go
• š is pronounced like sh in shoe
• r in strašan is a rolled or tapped r
• Serbian words are usually pronounced quite consistently compared with English spelling

So the sentence sounds roughly like: GLEH-dam STRAH-shan film

Because grammatical gender in Serbian is a property of the noun itself.

Film is a masculine noun, and you can tell that partly because its dictionary form ends in a consonant, which is very common for masculine nouns in Serbian.

Since film is masculine, the adjective must also be in the masculine form:

• strašan film

If the noun were feminine or neuter, the adjective would change:

• strašna knjiga = a terrible book
• strašno dete = a terrible/scary child

Yes.

The Serbian present tense often covers both:

• a simple present meaning
• and a present continuous meaning

So Gledam strašan film can mean:

• I watch a terrible film
• I am watching a terrible film

In real life, without extra context, most people would probably understand it as:

• I’m watching a terrible film

That is because gledam + object often describes an action happening now.

Yes, gledati can mean both watch and look at, depending on context.

For example:

• Gledam film = I’m watching a film
• Gledam u nebo = I’m looking at the sky

In your sentence, because the object is film, the natural translation is watch rather than look at.

Film is the normal and standard Serbian word for film/movie.

So:

• Gledam film = I’m watching a film/movie

Serbian does not have a native everyday word that works exactly like the English contrast between film and movie. In most ordinary situations, film covers both.
