कुर्सी मेज़ के सामने है, और बैग कुर्सी के पीछे है।

Hindi usually uses postpositions, not prepositions. That means the relational word comes after the noun.

So instead of English in front of the table, Hindi says:

• मेज़ के सामने = table + ke + in front
• कुर्सी के पीछे = chair + ke + behind

This is a very common Hindi pattern:

• घर के पास = near the house
• स्कूल के बाहर = outside the school
• दरवाज़े के सामने = in front of the door

So the main thing to remember is: Hindi puts these location words after the noun phrase, not before it.

• सामने means in front, facing, or opposite
• पीछे means behind or at the back of

In this sentence:

• कुर्सी मेज़ के सामने है = The chair is in front of the table.
• बैग कुर्सी के पीछे है = The bag is behind the chair.

These are very common location words in Hindi.

It is related, but in this sentence it is part of a fixed postpositional structure.

In expressions like:

• के सामने
• के पीछे
• के पास
• के बाहर

the के acts as a linker before the location word.

So although का / की / के are often taught as possessive markers, in phrases like these you should learn the whole expression together:

• X के सामने = in front of X
• X के पीछे = behind X

It is best not to translate के by itself here. Learn the chunk as one unit.

In these compound postposition expressions, Hindi normally uses के.

So you say:

• मेज़ के सामने
• कुर्सी के पीछे
• लड़की के सामने
• किताब के पास

Even if the noun is feminine, you still usually get के in this pattern.

So this is not ordinary adjective-like agreement. It is part of the set expression used with these relational words.

Because nouns before postpositions go into the oblique case, but some nouns do not show a visible change in the singular.

In this sentence:

• मेज़ stays मेज़
• कुर्सी stays कुर्सी

But with some nouns, you would see a change. For example:

• लड़का → लड़के के सामने
• कमरा → कमरे के पीछे

So the grammar is still working the same way here; it’s just that these particular nouns do not visibly change in singular oblique form.

Hindi word order is often Subject + location phrase + है.

So:

• कुर्सी मेज़ के सामने है literally feels like:
• Chair table in-front-of is

And:

• बैग कुर्सी के पीछे है literally feels like:
• Bag chair behind is

English puts the verb earlier and uses prepositions:

• The chair is in front of the table.

Hindi usually saves the main verb है for the end of the clause.

Because there are two separate clauses joined by और:

1. कुर्सी मेज़ के सामने है
2. बैग कुर्सी के पीछे है

Each clause has its own subject and its own is, so each clause gets है.

In English we also say:

• The chair is in front of the table, and the bag is behind the chair.

So the repetition is normal.

Because each subject is singular:

• कुर्सी = chair = singular
• बैग = bag = singular

So:

• कुर्सी ... है
• बैग ... है

If the subject were plural, you would use हैं:

• कुर्सियाँ मेज़ के सामने हैं। = The chairs are in front of the table.
• बैग कुर्सी के पीछे हैं। = The bags are behind the chair.

Hindi usually does not use articles the way English does.

So:

• कुर्सी can mean a chair or the chair
• मेज़ can mean a table or the table
• बैग can mean a bag or the bag

The exact meaning depends on context.

That is why the Hindi sentence can naturally translate as:

• The chair is in front of the table, and the bag is behind the chair.

But in another context, it could also mean:

• A chair is in front of a table, and a bag is behind the chair.

और means and.

It simply joins the two clauses:

• कुर्सी मेज़ के सामने है
• बैग कुर्सी के पीछे है

So:

• ..., और ... = ..., and ...

This is one of the most common conjunctions in Hindi.

मेज़ is a borrowed word, ultimately from Persian/Urdu usage, and it means table.

The letter ज़ has a dot underneath to show a z sound, different from plain ज.

So:

• ज sounds like j in jam
• ज़ sounds like z in zoo

So मेज़ is pronounced roughly like mez.

Many common Hindi words, especially borrowed ones, use dotted letters:

• ज़
• फ़
• ख़
• ग़

In everyday writing, some people omit the dot, but in careful writing it is useful.

Sometimes, but not always with exactly the same nuance.

• सामने usually means in front of or facing
• आगे often means ahead or further forward

For physical placement like this sentence, मेज़ के सामने is very natural.

If you say मेज़ के आगे, it may also be understood, but सामने is usually the clearer and more standard choice for in front of in this kind of simple location sentence.

Yes. It is simple, grammatical, and natural.

It uses very common patterns:

• noun + location phrase + है
• compound postpositions like के सामने and के पीछे
• और to join two clauses

So this is exactly the kind of sentence a learner should get comfortable with early on.
