Questions & Answers about Ta sukienka jest ładna, ale tamta jest tańsza.
Because sukienka is a feminine singular noun, and the words that describe or point to it must match its gender and number.
In this sentence:
- ta sukienka = this dress
- jest ładna = is pretty
- tamta jest tańsza = that one is cheaper
All of these feminine singular forms take -a here:
- ta = this (feminine)
- ładna = pretty (feminine)
- tańsza = cheaper (feminine)
If the noun were masculine or neuter, the forms would be different.
Both are demonstratives, but they point to different things:
- ta = this
- tamta = that
So:
- ta sukienka = this dress
- tamta = that one / that dress
A useful way to think about tamta is that it refers to something more distant, like that one over there.
