रात का खाना तैयार है।

A word-by-word breakdown is:

• रात = night
• का = of / belonging to
• खाना = food / meal / eating, but here it means meal
• तैयार = ready
• है = is

So literally, it is something like the night’s meal is ready, which naturally means dinner is ready.

In Hindi, का / की / के is used to link nouns, often like of in English.

So:

• रात का खाना = the food/meal of the night
• natural English translation: dinner

You cannot normally just put रात and खाना together without the linker. The का connects them.

This pattern is very common:

• सुबह का नाश्ता = breakfast
• दोपहर का खाना = lunch
• रात का खाना = dinner

Yes, रात literally means night. But in this expression, रात का खाना means the meal eaten at night, so it corresponds to dinner or the evening meal.

Hindi often describes meals by time of day rather than using a completely separate word like English does.

So:

• रात = night
• रात का खाना = night meal = dinner

Good question. खाना can be both:

1. a verb infinitive: to eat
2. a noun: food or meal

In this sentence, it is a noun.

Compare:

• मुझे खाना है। = I have to eat / I want to eat (verb-related use)
• खाना तैयार है। = The food is ready (noun use)

So in रात का खाना, खाना means meal/food, not to eat.

का / की / के agree with the noun that comes after them.

Here, the main noun is खाना, and खाना is:

• masculine
• singular

So the correct form is का:

• रात का खाना

If the following noun were feminine singular, you would use की:

• रात की चाय = night tea / evening tea

If it were plural or masculine plural, you would use के.

In Hindi, तैयार is an adjective meaning ready, and है is the verb is.

So:

• तैयार = ready
• है = is

Together: is ready

This is very normal in Hindi. It works like:

• कमरा साफ़ है। = The room is clean.
• खाना गर्म है। = The food is hot.
• रात का खाना तैयार है। = Dinner is ready.

Because the subject here is singular:

• रात का खाना = dinner / the night meal

That is treated as one thing, so Hindi uses है = is.

If the subject were plural, you would use हैं:

• पकवान तैयार हैं। = The dishes are ready.

No, तैयार usually does not change form for gender or number in this kind of usage.

So you can say:

• खाना तैयार है।
• रोटी तैयार है।
• कपड़े तैयार हैं।

The adjective तैयार stays the same. The verb है / हैं changes according to number.

This is because तैयार is one of the adjectives that are effectively indeclinable in common use.

The most natural order is:

• रात का खाना तैयार है।

This follows a very common Hindi pattern:

subject + adjective/complement + है

You can change the order in some contexts, but it may sound marked or more literary:

• खाना तैयार है। = The food is ready.
• रात का खाना तैयार है। = Dinner is ready.
• तैयार है रात का खाना। = The dinner is ready.
  This is possible, but less neutral in everyday speech.

So for learners, रात का खाना तैयार है is the best standard version.

Yes. भोजन also means meal/food.

So:

• रात ka खाना तैयार है = very common, everyday
• रात का भोजन तैयार है = correct, but more formal or bookish

In normal conversation, खाना is much more common.

Yes, depending on context, it can also be understood a bit more literally as:

• the night meal is ready
• the food for tonight is ready

But in most everyday situations, the natural meaning is simply dinner is ready.

A simple learner-friendly pronunciation guide is:

raat kaa khaa-naa tai-yaar hai

A few points:

• रात = raat
• का = kaa
• खाना = khaa-naa
  The ख is aspirated, like a stronger k with a puff of air.
• तैयार = tai-yaar
• है is often pronounced close to hai

Try saying it smoothly:

raat kaa khaa-naa tai-yaar hai

Yes. In everyday speech, people often shorten it if the context is clear:

• खाना तैयार है। = The food is ready.
• डिनर तैयार है। = Dinner is ready.
  This is also used in modern Hindi, especially in urban speech.

But रात का खाना तैयार है is a very natural full sentence and good standard Hindi.
