На цьому перехресті немає світлофора, тому пішохід іде дуже обережно.

Because на цьому перехресті means at this intersection and answers the question where? In Ukrainian, when на means location, it usually takes the locative case.

• перехрестя = intersection
• на перехресті = at the intersection
• на цьому перехресті = at this intersection

By contrast, на це перехрестя would suggest movement onto/to this intersection, answering where to?

So here the sentence is describing a place, not motion, which is why the locative is used.

Цей means this, and like adjectives/demonstratives in Ukrainian, it changes to match the noun’s:

• gender
• number
• case

Here, перехресті is in the locative singular, so цей becomes цьому:

• nominative: це перехрестя
• locative: на цьому перехресті

This is very common in Ukrainian: the word for this must agree with the noun it modifies.

After немає (there is no / there isn’t), Ukrainian usually puts the noun in the genitive case.

So:

• nominative: світлофор = traffic light
• genitive: світлофора

That is why the sentence says:

• немає світлофора = there is no traffic light

This is one of the most important patterns to remember in Ukrainian:

• є + nominative for existence
• немає + genitive for absence

For example:

• Тут є магазин. = There is a shop here.
• Тут немає магазину. = There is no shop here.

Немає means there is no / there are no / is not present. It is used to say that something does not exist or is absent in a place or situation.

In this sentence:

• На цьому перехресті немає світлофора = At this intersection, there is no traffic light.

Не є is much less common in everyday speech for this kind of idea. It means something more like is not in an identifying or formal sense, as in:

• Він не є лікарем. = He is not a doctor.

So for absence or non-existence, немає is the natural choice.

Here тому means therefore / so / that’s why.

It connects the two parts of the sentence:

• there is no traffic light at this intersection,
• therefore the pedestrian walks very carefully.

So:

• ..., тому пішохід іде дуже обережно.
• ..., so the pedestrian walks very carefully.

A useful point: this тому is not the same as тому що, which means because.

Compare:

• Немає світлофора, тому пішохід іде обережно. = There is no traffic light, so the pedestrian walks carefully.
• Пішохід іде обережно, тому що немає світлофора. = The pedestrian walks carefully because there is no traffic light.

Both іде and йде are acceptable forms meaning goes / is walking. They come from the verb йти.

In modern Ukrainian, both are used, and the choice is often influenced by style, rhythm, or surrounding sounds. In many contexts they are interchangeable.

So:

• пішохід іде
• пішохід йде

Both can mean the pedestrian is walking/goes.

Learners should recognize both forms as normal.

Ukrainian present tense often covers both a general present and what English might express as a progressive form.

So іде can mean:

• goes
• is going
• is walking

The exact English translation depends on context.

Here, because we are imagining a current situation at an intersection, English might naturally translate it as is walking very carefully, but Ukrainian simply uses the ordinary present tense: іде.

Because the sentence describes how the pedestrian walks, so Ukrainian uses an adverb, not an adjective.

• обережний = careful, cautious (adjective; describes a noun)
• обережно = carefully, cautiously (adverb; describes a verb)

Here the verb is іде (walks / goes), so we need the adverb:

• іде обережно = walks carefully

If you used обережний, you would be describing the pedestrian directly:

• Пішохід обережний. = The pedestrian is careful.

Дуже means very. It intensifies the adverb обережно.

So:

• обережно = carefully
• дуже обережно = very carefully

This is a very common pattern in Ukrainian:

• дуже швидко = very quickly
• дуже тихо = very quietly
• дуже добре = very well

Yes, Ukrainian word order is fairly flexible, though different orders can sound more natural depending on what is being emphasized.

The original sentence:

• На цьому перехресті немає світлофора, тому пішохід іде дуже обережно.

This is neutral and natural.

You could also say:

• Пішохід іде дуже обережно, тому що на цьому перехресті немає світлофора.

That changes the structure a little and shifts the focus.

In Ukrainian, word order often helps with emphasis rather than basic grammatical relations, since case endings already show those relations.

Because перехрестя is in the locative case after на when indicating location.

Its dictionary form is:

• перехрестя = intersection

In the locative singular, it becomes:

• на перехресті = at the intersection

This may look unusual because перехрестя is a neuter noun ending in -я, and many such nouns have special case changes. So it is a good idea to learn nouns together with common case forms, especially after prepositions like на, у, в, при.

In everyday Ukrainian, світлофор normally means a traffic light or traffic signal.

Depending on context, it can refer to:

• a traffic light for cars
• a pedestrian signal system as part of a crossing

But the default meaning is the ordinary street traffic light. In this sentence, it clearly refers to the lack of a traffic light at the intersection.

Grammatically, пішохід is singular and means pedestrian.

In context, it can mean:

• a specific pedestrian in the situation being described, or
• a generic pedestrian, like a pedestrian in an example sentence

So the sentence can feel like:

• the pedestrian walks very carefully, or
• a pedestrian walks very carefully

Ukrainian often leaves that kind of distinction to context, since it has no articles like a and the.

A natural English version might be:

• There’s no traffic light at this intersection, so the pedestrian walks very carefully.
• There isn’t a traffic light at this intersection, so the pedestrian is walking very carefully.

Both are reasonable. Ukrainian does not force the same article choice or the same distinction between walks and is walking, so English translations can vary a little while still matching the Ukrainian well.
