Questions & Answers about हालाँकि नियत तारीख कल है, फिर भी मैं उसे आज लौटाऊँगी।
Yes, they work together.
- हालाँकि introduces the concessive idea: although
- फिर भी reinforces the contrast in the main clause: even so / still / nevertheless
So the pattern is:
- हालाँकि X, फिर भी Y
- Although X, still Y
In English, using both can sometimes sound a bit heavy, but in Hindi this pairing is very common and natural.
You could omit फिर भी and say:
- हालाँकि नियत तारीख कल है, मैं उसे आज लौटाऊँगी।
That is still correct, but फिर भी makes the contrast clearer and more emphatic.
नियत तारीख means fixed date, set date, or in this context, due date.
Breakdown:
- नियत = fixed, निर्धारित, decided in advance
- तारीख = date
So together, नियत तारीख is the date that has already been set.
In everyday English for this sentence, due date is the most natural translation.
