Dlouhé podání zasáhne zadní čáru.

Because it agrees with podání, which is neuter singular.

• podání = a neuter noun
• In the nominative singular, the adjective dlouhý becomes:
  • dlouhý for masculine
  • dlouhá for feminine
  • dlouhé for neuter

So:

• dlouhé podání = a long serve

This is basic adjective-noun agreement in Czech.

It is in the nominative, because it is the subject of the sentence.

The sentence structure is:

• Dlouhé podání = the subject
• zasáhne = the verb
• zadní čáru = the object

So the serve is the thing doing the action: it hits the line.

Because čáru is in the accusative singular, not the nominative.

The base form is:

• čára = line

But after a transitive verb like zasáhnout (to hit, to strike), the direct object goes into the accusative:

• nominative: čára
• accusative: čáru

So:

• zadní čára = the back line / baseline
• zasáhne zadní čáru = hits the back line / baseline

The adjective zadní stays zadní here, because it belongs to a soft adjective pattern where the feminine nominative and accusative singular have the same form.

Here, podání means serve in a sports context.

Common translations of podání depend on context:

• in sports: serve
• in official/legal language: submission, filing, application

In this sentence, because of zasáhne zadní čáru and the sports setting, it clearly means serve.

Zasáhne means hits, strikes, or will hit, depending on context.

It comes from the verb zasáhnout.

In sports language, it often means something like:

• to hit
• to reach and touch
• to strike

So Dlouhé podání zasáhne zadní čáru means the long serve reaches/hits the back line.

Formally, it is the present-tense form of a perfective verb: zasáhnout.

In Czech, perfective verbs do not normally express an ongoing present action. Their present forms usually refer to the future.

So zasáhne often means:

• will hit

But in certain contexts, especially sports commentary, instructions, or descriptions of repeated game situations, English may translate it more naturally as:

• hits
• lands on

So depending on context, this can feel like either:

• The long serve will hit the back line, or
• The long serve hits the back line

Because Czech does not use articles like English a and the.

So:

• podání can mean a serve or the serve
• zadní čára can mean a back line or the back line

You understand which one is meant from context.

So Dlouhé podání zasáhne zadní čáru could be interpreted in English as:

• A long serve hits the back line
• The long serve hits the back line

depending on the situation.

Yes, literally it means long serve.

In sports English, though, depending on context, you might also say:

• deep serve
• a serve that reaches the baseline
• a long serve

So the Czech adjective dlouhé is straightforwardly long, but the most natural English wording can vary by sport.

The sentence uses a very normal Czech order:

• subject + verb + object

So:

• Dlouhé podání = subject
• zasáhne = verb
• zadní čáru = object

Czech word order is more flexible than English because cases show grammatical function. So you could rearrange the sentence for emphasis, for example:

• Zadní čáru zasáhne dlouhé podání.

But the original order is the most neutral and easiest for learners to understand.

The adjective zadní generally means:

• back
• rear
• behind

So:

• zadní čára = back line, often baseline depending on the sport

It comes from the idea of something located at the back.

A rough pronunciation guide is:

DLOU-heh POH-dah-nyee ZAH-sah-nyeh ZAD-nyee CHAA-roo

A few useful notes:

• dlouhé: ou sounds roughly like the o in go followed by a glide
• podání: ň is a soft n sound, like Spanish ñ
• zasáhne: the hne cluster may feel unusual at first
• č is like ch in church
• á is a long vowel

If you want to say it smoothly, try it in chunks:

• Dlouhé podání
• zasáhne
• zadní čáru

Here are the dictionary forms:

• dlouhé → dlouhý = long
• podání → podání = serve / submission
• zasáhne → zasáhnout = to hit, strike, reach
• zadní → zadní = back, rear
• čáru → čára = line

This is useful because Czech words often appear in changed forms depending on gender, case, number, and verb conjugation.

It sounds most natural in a sports context where a serve can reach a back line, such as tennis, volleyball, or a similar game.

The exact English translation of zadní čára may change by sport:

• back line
• baseline
• sometimes simply the line

So the Czech sentence is understandable on its own, but the most natural English wording depends on the game being described.
