चाकू और चम्मच मेज़ पर हैं।

A word-by-word breakdown:

• चाकू = knife
• और = and
• चम्मच = spoon
• मेज़ = table
• पर = on
• हैं = are

So the sentence is literally:

• knife and spoon table on are

Natural English:

• The knife and spoon are on the table.

Because Hindi usually follows Subject–Object/Other information–Verb word order, and the main verb often comes at the end of the sentence.

So in this sentence:

• चाकू और चम्मच = the knife and spoon
• मेज़ par = on the table
• हैं = are

This is very normal Hindi structure.

Hindi uses postpositions, not prepositions.

In English, the equivalent word comes before the noun:

• on the table

In Hindi, it comes after the noun:

• मेज़ पर = table on

So पर means on, but it comes after the noun it belongs to.

Because the subject is plural.

• है = is
• हैं = are

Here the subject is चाकू और चम्मच = the knife and spoon, which is more than one thing, so Hindi uses हैं.

Compare:

• चाकू मेज़ पर है। = The knife is on the table.
• चाकू और चम्मच मेज़ पर हैं। = The knife and spoon are on the table.

Hindi usually does not have articles like English a/an/the.

So चाकू can mean:

• a knife
• the knife

And मेज़ can mean:

• a table
• the table

The exact meaning usually depends on context. In many simple examples, English translations add the because that sounds natural in English.

Yes, nouns in Hindi have grammatical gender, but in this sentence it does not cause any visible change in the adjective or verb beyond the plural हैं.

A helpful point:

• चाकू is generally treated as masculine
• चम्मच is generally treated as masculine
• मेज़ is often treated as feminine

However, since there is no adjective here and the verb is just हैं, you do not really see much gender effect in this sentence.

In Hindi, nouns often take an oblique form before a postposition like पर, में, से, etc.

But some nouns either:

• have the same direct and oblique form, or
• do not visibly change in common usage

Here, मेज़ stays मेज़:

• direct: मेज़
• before पर: मेज़ पर

So even though it is followed by a postposition, there is no visible change here.

Yes, और is the normal everyday word for and in Hindi.

Examples:

• राम और श्याम = Ram and Shyam
• चाय और कॉफ़ी = tea and coffee
• चाकू और चम्मच = knife and spoon

Very common and useful word.

A simple pronunciation guide:

• चाकू ≈ chaa-koo
• और ≈ aur
• चम्मच ≈ chum-mach
• मेज़ ≈ mez
• पर ≈ par
• हैं ≈ hain (roughly like hen with a nasal quality)

Putting it together:

• chaa-koo aur chum-mach mez par hain

A more natural flow:

• chaakoo aur chammach mez par hain

Yes. In modern Hindi, both are used.

• मेज़ = table
• टेबल = table (borrowed from English)

So these are both understandable:

• चाकू और चम्मच मेज़ पर हैं।
• चाकू और चम्मच टेबल पर हैं।

मेज़ sounds more standard Hindi/Urdu, while टेबल is also very common in everyday speech.

By itself, the Hindi sentence does not force a distinction as clearly as English often does.

Depending on context, it could mean:

• The knife and spoon are on the table
• A knife and a spoon are on the table

In practice, many learners see it translated with the because that is often the most natural English rendering in a simple context.

Yes, Hindi word order is somewhat flexible, though the version you were given is the most neutral and natural.

Standard neutral order:

• चाकू और चम्मच मेज़ पर हैं।

You could also say:

• मेज़ पर चाकू और चम्मच हैं।

This also means:

• There are a knife and a spoon on the table / The knife and spoon are on the table

The difference is mostly about emphasis or flow, not basic meaning.
