Je přívod vody mezi pračkou a stěnou?

Because this is a yes/no question in Czech.

In neutral statements, Czech often uses the same word order as English in a statement:

• Přívod vody je mezi pračkou a stěnou. = The water supply is between the washing machine and the wall.

To turn it into a yes/no question, Czech commonly puts the verb first:

• Je přívod vody mezi pračkou a stěnou? = Is the water supply between the washing machine and the wall?

Unlike English, Czech does not need a separate helper verb like do/does.

Je is the 3rd person singular form of the verb být = to be.

Here it means is.

A few forms of být in the present tense are:

• jsem = I am
• jsi / jste = you are
• je = he/she/it is
• jsme = we are
• jsou = they are

So in this sentence, Je matches přívod because přívod is singular.

Přívod vody literally means water supply or water inlet/feed.

• přívod = supply, feed, inlet
• vody = of water

In real-life context, it could refer to:

• the water supply line
• the inlet hose
• the water connection

So this is a noun phrase, not a full clause.

Because vody is in the genitive case.

In Czech, when one noun specifies another noun, the second noun is often put in the genitive:

• přívod vody = supply of water
• sklenice vody = a glass of water
• láhev vína = a bottle of wine

The basic form is:

• voda = water

But after přívod, Czech uses:

• vody = of water

So přívod vody is literally the supply of water.

Because the preposition mezi can require the instrumental case when it expresses location.

Here the sentence is asking where something is located:

• mezi pračkou a stěnou = between the washing machine and the wall

So:

• pračka → pračkou
• stěna → stěnou

These are instrumental singular forms.

This happens because the meaning is static location, not motion.

Not always.

Mezi can take:

• instrumental for location: between, among
• accusative for *movement toward a position between

Examples:

• Je mezi pračkou a stěnou. = It is between the washing machine and the wall.
  → location, so instrumental

• Dám to mezi pračku a stěnu. = I’ll put it between the washing machine and the wall.
  → movement, so accusative

So in your sentence, mezi pračkou a stěnou is instrumental because it means where it is.

Because Czech has no articles.

English distinguishes:

• a washing machine
• the washing machine

Czech usually just says:

• pračka

The exact meaning depends on context.

So:

• přívod vody could mean the water supply or a water supply
• pračka could mean the washing machine or a washing machine
• stěna could mean the wall or a wall

In this sentence, the context makes it natural to understand them as specific things: the water supply, the washing machine, the wall.

Because pračka is the nominative (dictionary form), but after mezi in this sentence, Czech needs the instrumental.

So the noun changes form:

• pračka = washing machine
• pračkou = with/by/between the washing machine, depending on context

For feminine nouns ending in -a, the instrumental singular often ends in -ou:

• žena → ženou
• stěna → stěnou
• pračka → pračkou

So this is a normal case ending, not a different word.

Yes. That would also be correct.

Czech word order is fairly flexible, and the order of the two objects after mezi can be swapped:

• mezi pračkou a stěnou
• mezi stěnou a pračkou
• mezi zdí a pračkou

All can work, depending on style and context.

Also note:

• stěna = wall
• zeď = wall

Both can mean wall, though usage can vary a bit by context. Stěna is very common for an interior wall/surface, while zeď can sound more like a solid wall structure, but in everyday speech there is overlap.

No. Czech normally does not need a separate subject pronoun here.

The subject is already the noun phrase:

• přívod vody

So the sentence literally has:

• Je = is
• přívod vody = the water supply
• mezi pračkou a stěnou = between the washing machine and the wall

Czech often omits pronouns unless they are needed for emphasis or contrast.

The structure is:

• Je = verb
• přívod vody = subject
• mezi pračkou a stěnou = adverbial phrase of place / location

More specifically:

• přívod is the head noun of the subject
• vody modifies přívod
• mezi pračkou a stěnou tells you where the subject is

So this is a very typical Czech sentence pattern:

verb + subject + place

especially in yes/no questions.

A few parts may be tricky for English speakers:

• přívod
  The ř sound is famously difficult. It is a special Czech sound, somewhat like a rolled/flapped r mixed with zh. You do not need to master it immediately to be understood.

• pračkou
  The č sounds like ch in check.

• stěnou
  stě is roughly like styeh, with a softened t sound before ě.

A rough learner-friendly approximation might be:

• yeh pree-vot vo-dee meh-zi prach-koh ah styeh-noh

That is not perfect Czech pronunciation, but it can help as a starting point.

Yes, that is possible too.

Czech word order is more flexible than English, and changing the order can shift emphasis.

Compare:

• Je přívod vody mezi pračkou a stěnou?
  Neutral: Is the water supply between the washing machine and the wall?

• Je mezi pračkou a stěnou přívod vody?
  Slightly more focus on the location: Is there a water supply between the washing machine and the wall?

The first version is probably the most straightforward for a learner, but both are understandable and natural in the right context.
