Questions & Answers about मेरे घर और ऑफिस के बीच एक बड़ा बाज़ार है।

Why is it मेरे घर and not मेरा घर?

Because मेरे is being used before a noun phrase that is tied to a postposition later in the sentence.

In Hindi, nouns often change form when they come before postpositions such as में, से, के लिए, के बीच, etc. This is called the oblique case. Possessives often match that pattern too.

Here, the phrase is:

मेरे घर और ऑफिस के बीच = between my home and office

Since घर और ऑफिस is part of a phrase followed by के बीच, मेरा becomes मेरे.

Compare:

• मेरा घर बड़ा है। = My house is big.
• मेरे घर के पास एक पार्क है। = There is a park near my house.

So in your sentence, मेरे is the correct form.

Why is there only one मेरे? Does it mean my home and my office, or just my home and the office?

In this sentence, मेरे घर और ऑफिस usually means my home and office in a natural, economical way.

Hindi often avoids repeating possessives when the meaning is clear. So:

• मेरे घर और ऑफिस के बीच
  usually means between my home and office

If you want to be extra explicit, you could also say:

• मेरे घर और मेरे ऑफिस के बीच

That is also correct, but slightly more repetitive.

So both are possible:

• = natural, common
