شیر و تخم مرغ در یخچال هستند.

Because Persian usually prefers subject + other information + verb order.

So:

• شیر و تخم مرغ = the subject
• در یخچال = the location
• هستند = the verb are

A very literal word-for-word order would be:

milk and eggs in the refrigerator are

This verb-final pattern is very common in Persian.

Because the subject is made of two things joined by و:

• شیر = milk
• تخم مرغ = egg / eggs
• شیر و تخم مرغ = milk and eggs

Together, that is a compound subject, so Persian uses the plural form هستند = are.

• است = is
• هستند = are

So the sentence ends with are, not is.

و means and.

In careful reading, learners often first see it as va, but in normal pronunciation between words it is very commonly pronounced o.

So:

• شیر و تخم مرغ is usually pronounced roughly shir o tokhm-e morgh

That pronunciation is completely normal.

Persian does not have a separate word exactly like English the.

So یخچال can mean:

• a refrigerator
• the refrigerator
• fridge / refrigerator

The exact meaning depends on context.

Here, because the meaning is already clear, در یخچال naturally means in the fridge / in the refrigerator.

در is a preposition meaning in, inside, or sometimes at, depending on context.

In this sentence:

• در یخچال = in the refrigerator

It comes before the noun, like English in.

This is a very common learner question.

In Persian, a noun does not always need an explicit plural ending when the meaning is understood from context. A food item or category can sometimes be left in an unmarked form even when English would naturally say eggs.

So تخم مرغ here can be understood as egg / eggs, depending on the situation.

If you want to make the plural more explicit, you can say:

• تخم‌مرغ‌ها = the eggs

But the unmarked form is still very natural in many contexts.

It is usually pronounced roughly as:

tokhm-e morgh

A few useful notes:

• تخم = tokhm
• مرغ = morgh
• There is a linking sound -e- between them in pronunciation

So even though learners may look at the writing and expect a pause between the two words, in speech they are connected.

You may also see it written as:

• تخم مرغ
• تخم‌مرغ

Both refer to the same word/phrase.

Yes. شیر is a famous Persian word with multiple meanings, including:

• milk
• lion
• tap / faucet in some contexts

In this sentence, because it appears with تخم مرغ and یخچال, the meaning is clearly milk.

Context usually makes the intended meaning obvious.

Yes, شیر و تخم مرغ در یخچال هستند sounds normal and slightly more formal or written.

In everyday spoken Persian, people often say something like:

• شیر و تخم‌مرغ تو یخچالن

Changes you might notice:

• در often becomes تو in speech
• هستند becomes هستن or a shortened spoken form like -ن
• pronunciation becomes more connected and relaxed

So the written sentence is correct, but spoken Persian often sounds shorter and smoother.

Because Persian handles sentence structure differently from English.

English says:

• The milk and eggs are in the fridge

Persian puts the location before the verb:

• Milk and eggs in the fridge are

So instead of placing are between the subject and the location, Persian usually places the verb at the end.

That is one of the most important word-order differences for English speakers to get used to.
