Ať pořadatel označí každý stojan.

Ať introduces a kind of command, wish, or instruction aimed at a third person.

In this sentence, it means something like:

• let the organizer...
• the organizer should...
• have the organizer...

So Ať pořadatel označí každý stojan. is not telling you to do something directly. It is telling or proposing that the organizer do it.

Označí is the 3rd person singular form of the perfective verb označit.

With ať, Czech very often uses this kind of form to express a one-time completed action that should happen:

• Ať to udělá. = Let him/her do it.
• Ať pořadatel označí každý stojan. = Let the organizer label/mark each stand.

By contrast, označuje is from the imperfective verb označovat and usually describes an ongoing or repeated action, not a single completed instruction.

Formally, it looks like a present-tense form, but because označit is a perfective verb, its present-looking forms usually have future meaning.

So označí can mean:

• he/she will label/mark
• and after ať, it works as let him/her label/mark

This is a very common feature of Czech perfective verbs.

Czech usually does not need subject pronouns when the verb ending already shows the person and number.

Here:

• označí = he/she/it will label or let him/her label
• the noun pořadatel makes the subject explicit anyway

So adding a pronoun would be unnecessary.

Pořadatel is in the nominative singular because it is the subject of the sentence — the person who is supposed to do the action.

So:

• pořadatel = the organizer (subject)
• označí = will label / should label
• každý stojan = each stand (object)

Because stojan is the direct object of the verb označit, so it must be in the accusative case.

However, stojan is a masculine inanimate noun, and for masculine inanimate nouns, the accusative singular is often the same as the nominative singular.

So:

• nominative: každý stojan
• accusative: každý stojan

They look the same, but the function is different.

For the same reason: it agrees with stojan.

Since stojan here is:

• masculine
• singular
• inanimate
• accusative

the adjective/pronoun každý takes the matching form. In this pattern, masculine inanimate accusative singular looks the same as nominative singular, so you get:

• každý stojan

If the noun were masculine animate, the form would be different. For example:

• každého organizátora = each organizer (accusative masculine animate)

Stojan is a noun meaning something like:

• stand
• rack
• holder
• display stand

The exact English translation depends on context. In different situations, it could be a bike stand, a brochure stand, a display stand, a metal rack, and so on.

So the Czech grammar here is the important part; the exact English noun depends on the situation already given to the learner.

Yes. Czech word order is more flexible than English because case endings show grammatical roles.

For example, these could all be possible depending on emphasis:

• Ať pořadatel označí každý stojan.
• Každý stojan ať pořadatel označí.
• Pořadatel ať označí každý stojan.

The original order is neutral and natural. It puts the instruction first with ať, then the subject, then the verb, then the object.

Not in the same way as the imperative Označte každý stojan! = Label every stand!

This sentence is a third-person command or jussive-style instruction:

• Ať pořadatel označí každý stojan.
• literally: Let the organizer label each stand.

So it is a way to say what someone else should do, rather than directly commanding the listener.

The dictionary form is pořadatel.

It is a masculine noun meaning organizer. It refers to a person who organizes an event or activity.

Related forms include:

• pořadatel = male organizer / organizer in general
• pořadatelka = female organizer
• plural: pořadatelé

In this sentence, it is singular: one organizer.

A rough pronunciation guide:

• pořadatel ≈ po-rzha-da-tel
• označí ≈ oz-na-chee

A few notes:

• ř is a special Czech sound, something like a mix of r and zh
• č sounds like ch in check
• í is a long ee sound

So označí ends with a long chee.

Because ať is just a particle introducing the clause; it is not itself the verb.

The basic structure is:

• Ať
  • subject + verb + object

So:

• Ať = let / may / should
• pořadatel = the organizer
• označí = labels / will label / should label
• každý stojan = each stand

This order is very natural in Czech, though, as mentioned, other word orders are also possible for emphasis.
