मोबाइल ऐप नया है।

Hindi often puts the describing word before the noun when it is directly attached to it, but in this sentence नया is not part of the noun phrase मोबाइल ऐप. It is the predicate adjective: it tells us what the app is like.

So the structure is:

• मोबाइल ऐप = the mobile app
• नया = new
• है = is

Literally, it is:

• Mobile app new is.

This is a very normal Hindi sentence pattern: subject + description + है

For example:

• घर बड़ा है। = The house is big.
• फोन अच्छा है। = The phone is good.

If you say नया मोबाइल ऐप, that means new mobile app as a noun phrase, not a full sentence by itself.

नया means new.

It is an adjective, and here it describes ऐप.

Hindi adjectives often change form depending on the gender and number of the noun. Here the form is नया, which is the masculine singular form.

Compare:

• नया = masculine singular
• नई = feminine singular
• नए = masculine plural (and also some oblique uses)

So in this sentence, नया shows that मोबाइल ऐप is being treated as masculine singular.

Because ऐप is being treated as a masculine singular noun in this sentence.

In Hindi, adjectives agree with the noun they describe. Since the sentence uses नया, the speaker is treating ऐप as masculine.

So:

• मोबाइल ऐप नया है। = The mobile app is new.
  masculine singular

If the noun were treated as feminine, you would expect:

• मोबाइल ऐप नई है।

But with many borrowed tech words in Hindi, gender can vary by speaker and region. In actual usage, ऐप is often treated as masculine, which is why नया sounds natural here.

Two things show that:

1. नया is singular masculine
2. है is singular is

If it were plural, you would usually see:

• मोबाइल ऐप नए हैं। = The mobile apps are new.

So the adjective and the verb both help signal number.

है means is.

Hindi usually places the verb at the end of the sentence. That is one of the biggest differences from English.

So:

• English: The mobile app is new.
• Hindi: मोबाइल ऐप नया है।
  • subject
  • description
  • verb

This final है is very common in simple present-tense statements with nouns and adjectives.

Yes. Hindi does not have articles like a, an, and the.

So मोबाइल ऐप नया है। could mean:

• The mobile app is new
• A mobile app is new
• Mobile app is new in a more context-based sense

Which one is meant depends on context.

If you want to make a/an more explicit, Hindi can sometimes use एक:

• एक मोबाइल ऐप नया है। = A mobile app is new.

But in many cases, Hindi simply does not need anything corresponding to English articles.

Here मोबाइल is functioning like a modifier for ऐप.

So मोबाइल ऐप means mobile app.

Even though मोबाइल can also be a noun by itself, as in mobile phone, in this sentence it is describing what kind of app it is.

This is common with borrowed words in Hindi. A word can behave a bit flexibly depending on context.

ऐप is a borrowed word from English app.

Modern Hindi uses many English loanwords, especially for technology:

• फोन
• कंप्यूटर
• ऐप
• मोबाइल
• इंटरनेट

These words are often written in Devanagari and then used inside normal Hindi grammar.

So even though ऐप comes from English, the sentence itself is still perfectly natural Hindi.

You would normally say:

• मोबाइल ऐप नए हैं। = The mobile apps are new.

Changes:

• नया → नए
• है → हैं

So the pattern becomes:

• singular: मोबाइल ऐप नया है।
• plural: मोबाइल ऐप नए हैं।

In real life, plural marking on borrowed nouns can vary, but this is the basic and useful pattern to learn.

Yes, absolutely.

• यह मोबाइल ऐप नया है। = This mobile app is new.

Adding यह makes the subject more specific.

Without यह, the sentence is more general or depends more on context:

• मोबाइल ऐप नया है।

With यह, it is clearly:

• this mobile app

Both are correct.

A simple pronunciation guide is:

• मोबाइल = mo-baa-il or mo-bile
• ऐप = app
• नया = na-yaa
• है = hai

A rough full pronunciation is:

mo-baa-il app na-yaa hai

A more learner-friendly transliteration is:

mobāil app nayā hai

Keep in mind that Hindi pronunciation is usually more consistent than English spelling, so once you learn the sounds of the script, reading gets easier.
