Ruta vodi kroz grad.

Because ruta is in the nominative singular, which is the normal case for the subject of a sentence.

• ruta = route
• vodi = leads / goes / runs
• kroz grad = through the city

So structurally, the sentence is:

Ruta + vodi + kroz grad
The route + leads + through the city

Even though route is not a person, Serbian often uses verbs like voditi this way, just like English says The road leads to the village.

Here vodi means something like:

• leads
• goes
• runs
• takes you

The base verb is voditi, which literally often means to lead or to guide. But with things like roads, paths, routes, or stairs, it is very commonly used in the sense of leading somewhere.

So Ruta vodi kroz grad can be understood as:

• The route leads through the city
• The route goes through the city

Because in the present tense, Serbian verbs do not change for gender. They change for person and number.

Here, ruta is third person singular, so the verb must be vodi.

Present tense of voditi:

• ja vodim = I lead
• ti vodiš = you lead
• on/ona/ono vodi = he/she/it leads
• mi vodimo = we lead
• vi vodite = you (plural/formal) lead
• oni/one/ona vode = they lead

So even though ruta is feminine, it still takes vodi, just like ona vodi.

After kroz, Serbian normally uses the accusative case.

So in kroz grad, grad is accusative singular.

This is a useful pattern to remember:

• kroz grad = through the city
• kroz šumu = through the forest
• kroz selo = through the village

A detail that can confuse learners:
grad is a masculine inanimate noun, and in the singular its nominative and accusative forms are the same:

• nominative: grad
• accusative: grad

So you cannot see the case ending change here, but it is still accusative because kroz requires it.

Because grad is a masculine inanimate noun.

For masculine inanimate nouns in the singular, the accusative usually looks the same as the nominative:

• grad → grad
• park → park
• most → most

Compare that with masculine animate nouns, where the accusative often matches the genitive:

• čovek → vidim čoveka
• student → poznajem studenta

Since a city is inanimate, you get kroz grad, not kroz grada.

Ruta is a real and understandable Serbian word, and it is common especially in contexts like:

• maps
• GPS/navigation
• transport
• planned itineraries
• hiking/cycling routes

Depending on context, other words may also be used:

• put = road, way, path, route
• putanja = trajectory/path
• staza = trail/path
• pravac = direction/route in some contexts

So Ruta vodi kroz grad sounds natural if you are talking about a mapped or planned route. In some everyday contexts, a Serbian speaker might also say something like:

• Put vodi kroz grad. = The road/path leads through the city.
• Ruta prolazi kroz grad. = The route passes through the city.

Yes, absolutely.

There is a small nuance:

• Ruta vodi kroz grad = the route leads through the city, with a sense of direction or guidance
• Ruta prolazi kroz grad = the route passes through the city

Both are natural, but they highlight slightly different things:

• vodi focuses more on where the route takes you
• prolazi focuses more on the route’s physical course

In many practical contexts, both would work.

Because Serbian does not have articles like a/an/the.

So:

• ruta can mean a route or the route
• grad can mean a city or the city

You understand which one is meant from context.

So Ruta vodi kroz grad can mean:

• A route leads through the city
• The route leads through the city

In many learning materials, the English translation uses the because that sounds most natural in context, but Serbian itself does not mark that distinction with an article.

Yes, Serbian word order is more flexible than English word order.

The most neutral version here is:

Ruta vodi kroz grad.

But other orders are possible, depending on emphasis:

• Kroz grad vodi ruta. = more marked; emphasizes through the city
• Ruta kroz grad vodi. = possible, but less neutral and less common in ordinary speech

As a learner, the safest and most natural choice is the original:

Ruta vodi kroz grad.

A simple English-friendly approximation is:

ROO-tah VOH-dee krohz grahd

A few notes:

• r in Serbian is rolled or tapped
• u is like oo in food
• o is a clear o, not a diphthong
• a is like a in father
• i is like ee in see

Word by word:

• Ruta → ROO-tah
• vodi → VOH-dee
• kroz → krohz
• grad → grahd

Usually, yes, but it can also mean town depending on context.

So grad is a general word for an urban settlement. English may translate it as:

• city
• town

depending on the situation.

In this sentence, through the city is the most natural translation if that is the meaning already given to the learner.

Yes, voditi is an imperfective verb.

That matters because the sentence describes a general or ongoing fact:

• The route leads through the city
• The route goes through the city

Serbian commonly uses the imperfective present for this kind of general statement.

The sentence is not about one single completed act of leading; it is about the route’s characteristic direction. So vodi is exactly what you would expect here.
