यह लेन-देन मेरा नहीं है।

Here यह means this or this one.

In this sentence, it points to a specific transaction/dealing that is being referred to. In speech, यह is usually pronounced yeh.

A useful note:

• Written standard Hindi: यह = this
• Everyday speech: people often say ये in places where formal written Hindi uses यह

लेन-देन means transaction, dealings, exchange, or sometimes financial dealing, depending on context.

It is a fixed expression made from:

• लेन = taking
• देन = giving

So the literal sense is something like give-and-take, which naturally became transaction/dealing.

The hyphen shows that लेन-देन is a paired expression: two linked parts that function together as one idea.

Hindi has many such paired forms. In this case, the two parts are closely connected, so writing them with a hyphen helps show that the meaning is one unit: transaction / exchange / dealings.

You may sometimes also see variation in writing style, but लेन-देन with a hyphen is very common.

Because मेरा agrees with लेन-देन, which is treated here as masculine singular.

Hindi possessive words like मेरा / मेरी / मेरे change according to the noun they describe:

• मेरा = masculine singular
• मेरी = feminine singular
• मेरे = masculine plural, and also some oblique/plural contexts

Since लेन-देन is masculine singular here, मेरा is the correct form.

That is a very common learner question.

In Hindi, words like मेरा / मेरी / मेरे can work like:

• my before a noun
• mine when the meaning is understood from context

So in this sentence, मेरा नहीं है means is not mine.

Hindi does not always need a completely separate word like English mine. Instead, the possessive form itself does the job.

In Hindi, नहीं usually comes before the verb or the verbal part being negated.

So:

• है = is
• नहीं है = is not

That is why the sentence ends with मेरा नहीं है = is not mine.

This word order is very normal in Hindi.

है is the present-tense form of to be, so here it means is.

Without है, the sentence would feel incomplete in standard written Hindi. The full structure is:

• यह = this
• लेन-देन = transaction/dealing
• मेरा = mine
• नहीं है = is not

So the whole sentence literally follows the pattern: This transaction mine not is

That is normal Hindi word order.

Yes, in casual speech, people sometimes drop है, especially at the end of a sentence.

So you might hear:

• यह लेन-देन मेरा नहीं

But in standard, careful, or written Hindi, यह लेन-देन मेरा नहीं है is better and more complete.

Here it is understood as singular: this transaction/dealing.

Even though the idea of taking and giving sounds like a two-part concept, the expression लेन-देन functions as a single noun here.

If you were talking about multiple transactions, the sentence would change, for example:

• ये लेन-देन मेरे नहीं हैं = These transactions are not mine

To some extent, yes. Hindi word order is flexible, but not completely free.

The given sentence:

• यह लेन-देन मेरा नहीं है

A possible variation:

• यह मेरा लेन-देन नहीं है

Both are understandable, but the emphasis can shift slightly.

Very roughly:

• यह लेन-देन मेरा नहीं है focuses first on this transaction
• यह मेरा लेन-देन नहीं है brings my a little closer to the noun

The original sentence is perfectly natural.

No. It often refers to money, business, or financial transactions, but it can also mean more general dealings, exchanges, or interactions depending on context.

So the sentence could be understood in different ways depending on the situation:

• This financial transaction is not mine
• I am not connected with this dealing
• This exchange is not mine / not my responsibility

Context decides the most natural English meaning.

A simple pronunciation guide is:

yeh len-den mera nahin hai

A few helpful notes:

• यह = yeh
• लेन-देन = len-den with long e sounds
• मेरा = me-ra
• नहीं = na-hin or na-heen, with the final vowel slightly nasalized in careful pronunciation
• है = hai

So it flows like:

yeh len-den me-ra na-hin hai

It is neutral and standard Hindi.

It sounds natural in:

• conversation
• written statements
• customer-service situations
• official clarification

If you wanted to sound more formal or explicit, you might say something like:

• इस लेन-देन से मेरा कोई संबंध नहीं है = I have no connection with this transaction

But the original sentence is already correct and natural.
