चाकू यहाँ है।

• चाकू = knife
• यहाँ = here
• है = is

So the structure is literally knife here is.

Hindi usually puts the verb at the end of the sentence. That is a very common pattern in Hindi.

So:

• चाकू = subject
• यहाँ = location
• है = verb

This gives चाकू यहाँ है = The knife is here.

You may hear चाकू यहाँ है much more naturally than चाकू है यहाँ, although the second one can sometimes appear for emphasis in speech.

Hindi does not normally use articles like English a, an, and the.

So चाकू can mean:

• a knife
• the knife

The exact meaning depends on context. In a simple sentence like this, English often translates it as The knife is here or A knife is here, depending on the situation.

यहाँ means here.

It is usually pronounced roughly like yahaan, with a nasal sound at the end:

• य = ya
• हाँ here gives the long aa sound plus nasalization

A simple learner-friendly pronunciation is yuh-HAAN or ya-HAAN.

The little mark above the last part shows nasalization.

है is used with a singular subject.

Since चाकू is singular, we use:

• चाकू यहाँ है। = The knife is here.

हैं is generally used for:

• plural subjects
• respectful singular subjects

For example:

• चाकू यहाँ हैं। would usually sound wrong unless चाकू somehow referred to more than one thing, which it does not here.
• वे यहाँ हैं। = They are here.

चाकू is generally treated as masculine.

In this sentence, gender does not visibly change anything, because है does not show masculine/feminine difference in the present tense.

But gender matters in other sentences. For example:

• चाकू यहाँ था। = The knife was here.
  Here था shows masculine singular.
• If the noun were feminine, you would use थी in the past.

So yes, gender matters in Hindi, but not in an obvious way in this specific sentence.

Yes. यहाँ पर also means here.

So both are possible:

• चाकू यहाँ है।
• चाकू यहाँ पर है।

Usually यहाँ by itself is enough. Adding पर can sound a little more explicit or emphatic, but in many everyday sentences it is optional.

You would say:

चाकू कहाँ है?

Here:

• कहाँ = where
• है = is

So the pattern is very similar:

• चाकू यहाँ है। = The knife is here.
• चाकू कहाँ है? = Where is the knife?

A common way is:

क्या चाकू यहाँ है?

Here क्या at the beginning marks a yes/no question.

So:

• चाकू यहाँ है। = The knife is here.
• क्या चाकू यहाँ है? = Is the knife here?

In conversation, intonation can also sometimes make it a question, but क्या is the clearest beginner-friendly pattern.

Yes, चाकू is a very common everyday word for knife.

You may also come across more specific words depending on context, but चाकू is the normal general word most learners should know first.

Read it as:

चाकू यहाँ है।
chākū yahā̃ hai

A smooth reading is roughly: chaa-koo ya-haan hai

If you want to practice in chunks:

1. चाकू
2. यहाँ
3. है
4. then combine them: चाकू यहाँ है।

The vertical mark । at the end is the Hindi full stop, called danda. It works like a period in English.
