Questions & Answers about बचपन में मैं गाँव में रहती थी।
Because they belong to two different phrases:
- बचपन में = in childhood / during childhood
- गाँव में = in the village
In Hindi, में is a postposition meaning in, inside, or sometimes during, depending on context. So the sentence literally has:
- बचपन में → during childhood
- मैं → I
- गाँव में → in the village
- रहती थी → used to live / lived
So using में twice is completely normal here.
बचपन means childhood.
With में, it becomes in childhood or during childhood.
So:
- बचपन = childhood
- बचपन में = in childhood / when I was a child
This is a very common way to talk about a period of life in Hindi.
