संदेश में ओटीपी है।

में is a postposition meaning in or inside. So संदेश में means in the message.

Hindi uses postpositions after nouns, where English usually uses prepositions before nouns:

• in the message → संदेश में
• on the table → मेज़ पर

In Hindi, the verb usually comes at the end of the sentence. So the basic order is often:

subject/location + thing + verb

Here, literally, the structure is close to:

In the message, OTP is.

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

ओटीपी is just OTP written in Devanagari script. It is not a traditional Hindi word; it is an English abbreviation adapted to Hindi writing.

It is pronounced roughly like the English letters:

• O
• T
• P

So ओटीपी = OTP

Yes. Hindi often expresses there is / there are using है / हैं depending on number and context.

So:

• संदेश में ओटीपी है। = There is an OTP in the message.

Hindi does not need a separate word exactly like English there in this kind of sentence.

है is singular, and हैं is plural or respectful.

Since ओटीपी is being treated as one thing, the sentence uses है:

• ओटीपी है = There is an OTP
• ओटीपी हैं would sound like There are OTPs, which is not the intended meaning here

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

So:

• संदेश में ओटीपी है। can naturally mean There is an OTP in the message.

If you want to explicitly emphasize one, you could say:

• संदेश में एक ओटीपी है।

But in many normal situations, एक is not necessary.

Good question. Many Hindi nouns do take an oblique form before a postposition, but not all nouns show a visible change.

In this sentence:

• संदेश → संदेश में

There is no visible change in the form of संदेश. That is normal.

So even though it is functioning before a postposition, it still looks the same.

में is pronounced roughly like mein with nasalization: mẽ.

The vowel is nasalized, so it is not exactly plain me. The dot above the letter indicates nasalization here.

A simple learner-friendly pronunciation for the full sentence is:

sandesh mẽ OTP hai

Yes. In everyday speech, many Hindi speakers use the borrowed word मेसेज for message, especially in tech or texting contexts.

So both are possible:

• संदेश में ओटीपी है। — more standard Hindi
• मेसेज में ओटीपी है। — very common in casual modern speech

Yes, Hindi word order is somewhat flexible, though some versions sound more natural than others.

The most neutral version here is:

• संदेश में ओटीपी है।

You might also hear:

• ओटीपी संदेश में है।

This puts more focus on OTP. But for a simple statement, the original sentence is the most straightforward.

It is fairly neutral.

• संदेश is a standard Hindi word
• ओटीपी is a modern borrowed technical term

So the sentence sounds natural in many contexts, especially written instructions, apps, notifications, or customer-service language.

To make it negative, add नहीं before है:

• संदेश में ओटीपी नहीं है।

This means:

• There is no OTP in the message.
• The message does not contain an OTP.

A helpful breakdown is:

• संदेश = message
• में = in
• ओटीपी = OTP
• है = is

So very literally:

message in OTP is

Natural English:

There is an OTP in the message.
