Тарифний план дорогий.

In Ukrainian, the verb to be is usually omitted in the present tense.

So:

Тарифний план дорогий
literally looks like Tariff plan expensive, but it means The tariff plan is expensive.

This is completely normal Ukrainian sentence structure.

Ukrainian does not have articles like English the and a/an.

So Тарифний план дорогий can mean:

• The tariff plan is expensive
• A tariff plan is expensive

Context tells you which meaning is intended.

If you want to be more specific, you can add words like:

• цей тарифний план = this tariff plan
• один тарифний план = one / a certain tariff plan (depending on context)

Тарифний is an adjective meaning tariff-related or rate-related. It modifies план.

So:

• план = plan
• тарифний план = tariff plan / rate plan

The adjective тарифний agrees with план in gender, number, and case.

Because план is masculine singular nominative, the adjective also appears in the masculine singular nominative form:

• тарифний

Because here you are describing a masculine singular noun: план.

• дорогий = adjective, masculine singular, used with план
• дорого = adverb / predicative form, used in different sentence patterns

So:

• Тарифний план дорогий = The tariff plan is expensive
• Це дорого = This is expensive
• Тут дорого = It is expensive here

An English speaker often wants to use one unchanging word like expensive, but in Ukrainian the form changes depending on the structure.

Because both words are masculine singular nominative forms.

• тарифний agrees with план as an adjective before the noun
• дорогий also matches план, because it describes what the subject is like

Here the subject is:

• план = masculine
• singular
• nominative

So both adjectives appear in matching forms:

• тарифний план
• план дорогий

If the noun were feminine, the forms would change. For example:

• послуга дорога = The service is expensive

План is in the nominative case, because it is the subject of the sentence.

The whole sentence works like this:

• Тарифний план = the subject
• дорогий = what is being said about the subject

So this is a basic nominative sentence pattern:

[subject in nominative] + [adjective describing it]

That is why you see:

• тарифний — nominative
• план — nominative
• дорогий — nominative

A little, but word order affects meaning and emphasis.

The neutral sentence is:

Тарифний план дорогий.
= The tariff plan is expensive.

But:

Дорогий тарифний план
is usually understood as a noun phrase, not a full sentence:

= an expensive tariff plan

So if you want a complete, neutral statement, Тарифний план дорогий is the best choice.

Ukrainian word order is more flexible than English, but not every reordering means exactly the same thing.

No. Дорогий can also mean dear in the emotional sense.

For example:

• дорогий друг = dear friend
• дорогий подарунок = expensive gift

In Тарифний план дорогий, the meaning is clearly expensive, because the noun is a plan, not a person.

So context decides which meaning is intended.

Yes, тарифний план is natural and correct, especially in telecom, mobile, or internet service contexts.

But in everyday speech, people often shorten it to just:

• тариф = tariff / plan

So you may also hear:

Цей тариф дорогий.
= This plan is expensive.

Both are fine. Тарифний план sounds a bit more explicit or formal.

A helpful stress guide is:

тари́фний план дороги́й

Roughly:

ta-REEF-nyy plahn do-ro-HYY

A few pronunciation notes:

• г in Ukrainian is usually pronounced like a soft voiced h, not like English g
• и is not the same as English ee
• й is like y in boy or yes, depending on position

So дороги́й should not sound like English dorogee. The ending is more like -hyy.
