यहाँ नेटवर्क कवरेज कमज़ोर है।

यहाँ means here.

It is placed at the beginning because Hindi often puts the location early in the sentence, especially when setting the scene. So:

• यहाँ = here
• नेटवर्क कवरेज = network coverage
• कमज़ोर है = is weak

A very literal order would be:

Here network coverage weak is.

That sounds strange in English, but it is normal in Hindi.

They are loanwords from English, but they are very commonly used in Hindi.

So नेटवर्क कवरेज is basically the English phrase network coverage, written in Devanagari script.

This is extremely normal in modern Hindi, especially for technology-related terms. Hindi speakers often mix English-origin words into everyday speech.

You may also hear alternatives depending on context, such as:

• सिग्नल = signal
• नेटवर्क = network
• रेंज = range

But नेटवर्क कवरेज is perfectly natural.

Hindi usually follows Subject–Object–Verb order, and the verb often comes at the end.

In this sentence, the basic structure is:

• यहाँ = location
• नेटवर्क कवरेज = subject
• कमज़ोर = adjective/complement
• है = is

So Hindi places है at the end, where English would use is earlier.

English: Network coverage is weak here.

Hindi: यहाँ नेटवर्क कवरेज कमज़ोर है।

This is one of the most important sentence-pattern differences between Hindi and English.

कमज़ोर literally means weak.

In this sentence, it means:

• weak
• poor
• not strong
• not very good

So for network coverage, कमज़ोर can be understood as weak or poor.

For example:

• नेटवर्क कमज़ोर है = The network is weak.
• उसकी तबीयत कमज़ोर है = His/Her health is weak.
• वह गणित में कमज़ोर है = He/She is weak in math.

So कमज़ोर is a very flexible adjective.

है is the present-tense form of to be for he/she/it/this/that/singular things.

In Hindi, this kind of verb usually comes at the end of the sentence.

So:

• कमज़ोर है = is weak

Compare:

• वह खुश है। = He/She is happy.
• कमरा साफ़ है। = The room is clean.
• यहाँ नेटवर्क कवरेज कमज़ोर है। = Network coverage is weak here.

The final है is completely normal and expected in this type of sentence.

Good question. In Hindi, some adjectives change for gender and number, but some do not.

कमज़ोर is one of the adjectives that usually does not change form. It stays the same whether the noun is masculine or feminine, singular or plural.

For example:

• लड़का कमज़ोर है। = The boy is weak.
• लड़की कमज़ोर है। = The girl is weak.
• लड़के कमज़ोर हैं। = The boys are weak.
• लड़कियाँ कमज़ोर हैं। = The girls are weak.

So you do not need to change कमज़ोर.

By contrast, an adjective like अच्छा does change:

• अच्छा लड़का
• अच्छी लड़की

But कमज़ोर stays कमज़ोर.

Because नेटवर्क कवरेज is being treated as singular.

Even though it contains two English-origin words, the whole phrase means one thing: network coverage.

So Hindi uses singular है:

• नेटवर्क कवरेज कमज़ोर है।

If the subject were plural, you would use हैं:

• यहाँ नेटवर्क बहुत कमज़ोर हैं। = The networks here are very weak.
  (This is less likely in this exact context, but grammatically possible.)

So in your sentence, singular है matches the singular idea of coverage.

Yes, absolutely.

Both are natural, but there is a slight difference in feel:

• कमज़ोर है = weak
• खराब है = bad / poor / not good

For network quality, both work.
However:

• कमज़ोर often sounds more like the signal strength is low.
• खराब can sound more general: poor quality, bad condition, not good.

You may also hear:

• यहाँ सिग्नल कमज़ोर है। = The signal is weak here.
• यहाँ नेटवर्क नहीं आता। = There is no network here / The network doesn’t come here.
• यहाँ नेटवर्क बहुत खराब है। = The network is very poor here.

All of these are common in real speech.

Both relate to here, but they are not exactly the same.

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

So:

• यहाँ नेटवर्क कवरेज कमज़ोर है। = Network coverage is weak here.
• यहीं नेटवर्क कवरेज कमज़ोर है। = Network coverage is weak right here.

यहीं adds emphasis. It can suggest a more exact location.

Similarly:

• वहाँ = there
• वहीं = right there

A simple pronunciation guide:

• कमज़ोर ≈ kum-ZOR
• कवरेज ≈ kuv-rej or kuh-varej

A few helpful notes:

कमज़ोर

• कम sounds like kum
• ज़ो has a z sound
• stress naturally falls near ज़ोर

कवरेज

Since this is borrowed from English, pronunciation can vary a bit from speaker to speaker. Many Hindi speakers say something close to coverage, but adapted to Hindi sounds.

About ज़

The dot under ज़ shows a z sound.

• ज = more like j
• ज़ = more like z

In everyday writing, many people may still write कमजोर instead of कमज़ोर, and both are commonly understood.

Yes, it is natural and understandable.

That said, in everyday spoken Hindi, people often use shorter or more conversational versions such as:

• यहाँ नेटवर्क कमज़ोर है। = The network is weak here.
• यहाँ सिग्नल कमज़ोर है। = The signal is weak here.
• यहाँ नेटवर्क नहीं आता। = There’s no network here.
• यहाँ नेटवर्क की कवरेज कम है। = Network coverage is low here.

Your sentence sounds fine, especially in a practical or semi-formal context.
In casual conversation, many speakers would probably say सिग्नल कमज़ोर है or नेटवर्क कमज़ोर है.

Yes.

You can say:

• यहाँ नेटवर्क कवरेज बहुत कमज़ोर है। = Network coverage is very weak here.

बहुत means very or a lot, depending on context.

Other common intensifiers include:

• काफ़ी कमज़ोर है = quite weak
• थोड़ी कमज़ोर है = a little weak
  (less common with कवरेज, but possible depending on context)
• बेहद कमज़ोर है = extremely weak

So बहुत कमज़ोर है is a very useful pattern to remember.

Yes.

Both are correct:

• यहाँ नेटवर्क कवरेज कमज़ोर है।
• यहाँ पर नेटवर्क कवरेज कमज़ोर है।

The पर does not change the meaning much here. It can make the phrase feel slightly fuller or more emphatic, but often it is optional.

In everyday speech, Hindi speakers often use both forms:

• यहाँ
• यहाँ पर

So as a learner, it is good to recognize both.
