एडवांस बहुत ज़्यादा है।

Because Hindi very often borrows English words and writes them in Devanagari script. एडवांस is a common borrowed form of advance.

In everyday Hindi, especially in business, rent, salary, and payment contexts, speakers often use English-origin words like:

• एडवांस = advance / advance payment
• पेमेंट = payment
• ऑफिस = office
• ट्रेन = train

So this is completely normal modern Hindi, especially in speech and informal writing.

A natural approximation is:

• एडवांस = eḍvāns / ad-vaans

Roughly:

• ए sounds like e in bed, or sometimes a bit like ay
• ड is a retroflex d sound
• वां gives a vaa(n) sound
• स is s

A simple learner-friendly pronunciation is:

ed-vaans

Depending on accent, people may pronounce it a little differently because it is a loanword.

बहुत ज़्यादा is an intensifying combination. It means something like:

• very much
• too much
• far too much
• a lot too high

The two words are often used together in everyday Hindi for emphasis.

• बहुत = very / a lot
• ज़्यादा = more / much / too much / excessive, depending on context

So बहुत ज़्यादा is not strange or redundant in normal Hindi. It is a common, natural way to make the statement stronger.

Yes, but the nuance changes.

• एडवांस ज़्यादा है।
  = The advance is high / too much.

• एडवांस बहुत ज़्यादा है।
  = The advance is very high / far too much.

• एडवांस बहुत है।
  This is possible, but it sounds less natural in this kind of sentence than ज़्यादा है or बहुत ज़्यादा है. With prices, amounts, fees, etc., Hindi often prefers ज़्यादा.

So बहुत ज़्यादा है is the strongest and most natural colloquial version here.

है is the present-tense form of to be for singular subjects.

The structure is:

• एडवांस = the advance / advance payment
• बहुत ज़्यादा = very high / too much
• है = is

So the sentence literally works like:

Advance very much/too much is.

Natural English word order is different, but in Hindi this is normal.

Hindi usually places the main descriptive part before है.

So instead of:

• The advance is very high

Hindi gives:

• एडवांस
  • बहुत ज़्यादा
    • है

This is a very common Hindi pattern:

• कमरा बड़ा है। = The room is big.
• खर्चा ज़्यादा है। = The expense is high.
• एडवांस बहुत ज़्यादा है। = The advance is very high.

So the final है is completely expected.

In this sentence, ज़्यादा behaves like a predicate expression of degree/amount. For a learner, the easiest way to understand it is:

• it describes the amount/level of the advance
• so in English we often translate it as too much, higher, or excessive

Hindi ज़्यादा is very flexible. It can mean:

• more
• too much
• excessive
• higher

Examples:

• पैसे ज़्यादा हैं। = The money is too much / The amount is high.
• यह ज़्यादा अच्छा है। = This is better / This is more good.

So it does not map neatly onto just one English part of speech.

Hindi does not use articles the way English does. There is no direct equivalent of a/an/the in most ordinary sentences.

So एडवांस बहुत ज़्यादा है। can mean things like:

• The advance is very high.
• An advance is very high.
• The advance payment is too much.

The exact interpretation comes from context.

If Hindi wants to be more specific, it may use other words, such as:

• यह एडवांस = this advance
• वह एडवांस = that advance

But usually no article is needed.

Because एडवांस is being treated as a singular amount.

• है = is
• हैं = are

Even if the thing being discussed is money, Hindi often treats an amount as a single unit:

• किराया बहुत ज़्यादा है।
• खर्चा बहुत ज़्यादा है।
• एडवांस बहुत ज़्यादा है।

If you were talking about multiple separate items, then हैं could appear.

There are more formal or more Hindi/Sanskrit-based alternatives, such as:

• अग्रिम = advance
• अग्रिम राशि = advance amount
• पेशगी = advance payment (common in some contexts)

So you could also hear:

• अग्रिम राशि बहुत ज़्यादा है।
• पेशगी बहुत ज़्यादा है।

But एडवांस is extremely common in everyday modern Hindi, especially in urban/business contexts.

That dot is called a nukta. It changes the sound of the letter.

• ज = j
• ज़ = z

So:

• ज्यादा is often written informally, and many people still pronounce it similarly
• ज़्यादा is the more standard spelling for the z sound

In modern Hindi writing, both spellings may be seen, but ज़्यादा is very common and reflects the borrowed z-like pronunciation.

It is natural everyday Hindi, especially in spoken language.

• एडवांस makes it sound modern and conversational
• बहुत ज़्यादा is also common spoken emphasis

In a more formal setting, someone might say:

• अग्रिम राशि बहुत अधिक है।

That sounds more formal and official.

So:

• एडवांस बहुत ज़्यादा है। = everyday colloquial
• अग्रिम राशि बहुत अधिक है। = more formal

Yes, very often it does.

When someone says बहुत ज़्यादा है about a payment, price, or fee, it often suggests:

• this is excessive
• this is more than expected
• I am not happy with this amount

So in real conversation, the sentence often carries a tone like:

• That advance is too high.
• The advance is way too much.

The grammar itself is neutral, but the phrase strongly tends to sound like a complaint in context.
