Questions & Answers about यह मेरा वचन है।
- यह = this
- मेरा = my
- वचन = word / promise / vow
- है = is
So the structure is literally This my promise is, which in natural English becomes This is my promise or This is my word.
Hindi often uses a different basic order from English. In this sentence:
- English: This is my promise
- Hindi: This my promise is
The verb है usually comes at or near the end in simple Hindi sentences. That is very normal. So even though the order feels reversed to an English speaker, it is standard Hindi structure.
Because Hindi usually places the main verb after the rest of the sentence. In equational sentences like X is Y, the is word often comes last:
- यह घर है। = This is a house.
- वह मेरा दोस्त है। = That is my friend.
- यह मेरा वचन है। = This is my promise.
So है is not being emphasized here; it is simply in its normal Hindi position.
