रसोई में नाश्ता है; रोटी गरम है।

में is a postposition meaning in / inside / at in many contexts.

So:

• रसोई = kitchen
• रसोई में = in the kitchen

Hindi uses postpositions after the noun, unlike English prepositions, which come before the noun. So English in the kitchen becomes literally kitchen in in Hindi.

Both orders are possible, but रसोई में नाश्ता है is very natural.

Hindi often puts the location or context first, then the thing being talked about. So this clause feels like:

• In the kitchen, there is breakfast.

You can also say नाश्ता रसोई में है, which means more specifically The breakfast is in the kitchen.

So the difference is often one of focus:

• रसोई में नाश्ता है = emphasizes the kitchen / what is there
• नाश्ता रसोई में है = emphasizes where the breakfast is

है is the singular present form of to be.

In these two clauses, it works a little differently:

• रसोई में नाश्ता है = There is breakfast in the kitchen
• रोटी गरम है = The bread/flatbread is hot

So in the first clause, है is part of an existence idea: there is.
In the second clause, it links the subject and adjective: is hot.

Same word, slightly different use.

Hindi usually does not use articles the way English does.

So:

• नाश्ता है can mean there is breakfast
• रोटी गरम है can mean the bread is hot or a roti is hot, depending on context

Hindi relies much more on context than English for this.

If you need to be more specific, Hindi can add words such as:

• एक = a / one
• demonstratives like यह = this, वह = that

But in a simple sentence like this, leaving articles out is completely normal.

Good question. रोटी is feminine, but गरम is an indeclinable/invariable adjective in normal usage, so it usually does not change for gender or number.

So you get:

• गरम रोटी = hot roti
• गरम दाल = hot lentils
• गरम पानी = hot water

Some Hindi adjectives change form, but some do not.

For example:

• changing adjective: अच्छा लड़का, अच्छी लड़की
• non-changing adjective: गरम लड़का (unlikely meaning-wise, but grammatically unchanged), गरम रोटी

So रोटी गरम है is exactly what you should expect.

नाश्ता means breakfast and it is generally masculine.

You can see this in other sentences, especially where agreement shows up more clearly:

• नाश्ता अच्छा है = The breakfast is good
• मैंने नाश्ता किया = I ate breakfast / had breakfast

In your sentence, the verb है does not show gender, so you cannot tell gender just from नाश्ता है alone. But as a dictionary noun, नाश्ता is masculine.

रोटी usually refers to a round Indian flatbread, often translated as roti or sometimes more loosely as bread.

For learners, it is best to remember:

• रोटी = roti / flatbread

If a translation says bread, that is just a convenient English approximation. In many real-life contexts, रोटी means the specific South Asian food, not a loaf of Western-style bread.

In this sentence, रसोई clearly means kitchen.

Depending on context, रसोई can also relate to cooking or the cooking area, but for a beginner, kitchen is the right meaning here.

You may also see:

• रसोईघर = kitchen

Both are used, though रसोई is very common.

The semicolon simply joins two related statements:

• रसोई में नाश्ता है
• रोटी गरम है

It is similar to saying:

• There is breakfast in the kitchen; the roti is hot.

In everyday Hindi writing, you might also see a comma, a full stop, or the clauses written separately. The semicolon is just punctuation and does not change the grammar of the Hindi itself.

A simple pronunciation guide is:

rasoi mein nashta hai; roti garam hai

A slightly more accurate transliteration is:

rasoī meṅ nāshtā hai; roṭī garam hai

A few tips:

• रसोई sounds roughly like ra-so-ee
• में sounds like mein with a nasalized ending
• नाश्ता sounds like naash-taa
• रोटी sounds like ro-tee
• गरम sounds like ga-rum or ga-ram, depending on accent and speed

Yes. You will often see गरम and गर्म. Both are used for hot/warm.

So these are both common:

• रोटी गरम है
• रोटी गर्म है

The spelling गर्म is very common in modern writing, but गरम is also widely understood and used. For a learner, the important thing is that both refer to the same adjective here.
