Stiskni spínač.

Stiskni is the informal singular imperative of the verb stisknout = to press.

So Stiskni spínač. means a direct command to one person: Press the switch.

A useful breakdown:

• stisknout = infinitive, to press
• stiskni = press! (said to one person informally)

In Czech, the subject is often omitted because the verb form already shows who the command is directed to.

So in stiskni, the ending already tells you it means you (singular, informal) press!

Czech does this very often, especially in commands:

• Počkej! = Wait!
• Pojď sem! = Come here!
• Stiskni spínač. = Press the switch.

Adding ty would usually sound unnecessary unless you want extra emphasis.

Yes. Stiskni is used:

• to one person
• in an informal situation

For formal singular or plural, use:

• Stiskněte spínač.

That can mean:

• Press the switch. (formal, to one person)
• Press the switch. (to multiple people)

So:

• stiskni = informal singular
• stiskněte = formal singular or plural

Because spínač is the direct object of the verb stiskni, so it is in the accusative case.

The noun spínač is masculine inanimate, and for many masculine inanimate nouns, the accusative singular is the same as the nominative singular.

So:

• nominative: spínač
• accusative: spínač

That is why the sentence is:

• Stiskni spínač.

and not another form.

Not exactly. Spínač usually means switch.

This is different from:

• tlačítko = button
• vypínač = often switch, especially a wall switch; in everyday use, this is very common for a light switch

So spínač is a more general switch term. Depending on context, a Czech speaker might also use a different word if the object is specifically a button or a wall switch.

Stisknout is a perfective verb, and that fits this situation well because the command means do one complete action: press it once.

In Czech, perfective verbs are very common in instructions and commands when the action should be completed.

So:

• stisknout = to press once / press completely
• stiskni = press it

An imperfective form would suggest something more ongoing, repeated, or habitual, which usually does not fit a simple instruction like this.

That is why Stiskni spínač. sounds natural.

A rough pronunciation guide is:

• stiskni ≈ STISK-nyi
• spínač ≈ SPEE-naach (with č like ch in church)

A bit more carefully:

• sti- sounds like sti in stick, but shorter
• -skni has a consonant cluster; the ni sounds softened
• spí- has a long í, so it is pronounced longer: spee
• č is like ch in church

The stress in Czech is normally on the first syllable:

• STIskni
• SPÍnač

The normal neutral order is:

• Stiskni spínač.

Czech word order is more flexible than English, so Spínač stiskni is possible, but it changes the feel. It gives extra emphasis to spínač, something like:

• The switch, press it.

So for a basic instruction, Stiskni spínač. is the most natural choice.

The dictionary form is spínač.

Its gender is masculine inanimate.

That matters because Czech nouns change form depending on:

• gender
• number
• case

For this noun:

• singular nominative: spínač
• singular accusative: spínač

Knowing the gender helps you learn adjective agreement and other case forms later.

In many contexts, yes. English often uses press, push, or sometimes push down depending on the object.

Czech stisknout usually focuses on the idea of pressing by applying pressure. So the best English translation is often press, but in some contexts push may sound natural too.

The exact English wording depends on what the spínač looks like:

• a button-like control: press
• a physical switch or mechanism: sometimes push or press the switch

So the Czech sentence itself is straightforward, but the best English wording can vary with context.
