लेखक का नाम यहाँ है।

लेखक can mean writer or author, depending on context. In many learning materials, it is often translated as author when talking about a book, article, or written work.

It comes from the verb लिखना (to write), so the basic idea is a person who writes.

Yes. लेखक is grammatically masculine.

The feminine form is लेखिका.

So:

• लेखक का नाम यहाँ है। = if the author is male, or if masculine is being used generically
• लेखिका का नाम यहाँ है। = if the author is female

In real usage, masculine forms are sometimes used generically, but if you know the author is female, लेखिका is the more specifically correct form.

का is a possessive marker. It often corresponds to English of or 's.

So:

• लेखक का नाम literally means the author's name
• word-for-word: author's name

Hindi usually expresses this kind of relationship with:

• का
• की
• के

These change according to the noun that is being possessed.

Because नाम is grammatically masculine singular.

A very important Hindi rule is that का / की / के agrees with the thing possessed, not with the possessor.

Here:

• possessor = लेखक (author)
• possessed thing = नाम (name)

Since नाम is masculine singular, Hindi uses का:

• लेखक का नाम = the author's name

Compare:

• लेखक की किताब = the author's book
  because किताब is feminine
• लेखक के दोस्त = the author's friends
  because दोस्त is plural here

This is one of the most common things English speakers need to get used to.

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

So लेखक का नाम यहाँ है। does not need a separate word for the.

Hindi relies on context. Depending on the situation, the sentence could be understood as:

• The author's name is here
• An author's name is here
• The name of the author is here

In normal context, the intended meaning is usually clear without an article.

है means is.

It is the singular present-tense form of the verb to be.

So the sentence structure is roughly:

• लेखक का नाम = the author's name
• यहाँ = here
• है = is

Together:

• लेखक का नाम यहाँ है। = The author's name is here.

In standard written Hindi, है is normally included in this kind of sentence.

Because Hindi usually puts the verb at or near the end of the sentence.

So:

• लेखक का नाम यहाँ है। literally follows a pattern like:
• author's name here is

That is normal Hindi word order.

English uses:

• The author's name is here

Hindi prefers:

• The author's name here is

So the placement may feel reversed to an English speaker, but it is natural in Hindi.

Yes, you could. That would also be natural Hindi, but the emphasis changes a little.

• लेखक का नाम यहाँ है।
  Focuses more on the author's name; then says where it is.
• यहाँ लेखक का नाम है।
  Focuses more on here; like Here is the author's name or The author's name is here with extra attention on the location.

Both are grammatical. Hindi word order is more flexible than English, but changing the order often changes emphasis.

यहाँ is pronounced roughly yahaan / yahã.

The mark ँ shows nasalization. That means the vowel is pronounced through the nose slightly.

So it is not a strong separate n sound at the end in careful pronunciation. It is more like:

• yahaã

A simple learner-friendly pronunciation guide:

• य = y
• ह = h
• ाँ = a long aa sound with nasalization

So you can think of it as:

• yə-haã

Yes, it is natural and correct.

A speaker might also say:

• लेखक का नाम यहीं है।

Here यहीं means right here or here itself, which adds emphasis.

So:

• यहाँ = here
• यहीं = right here / exactly here

But your original sentence, लेखक का नाम यहाँ है।, is completely normal and correct.
