Questions & Answers about Ten wiersz jest smutniejszy niż tamten.
Because wiersz is a masculine singular noun in Polish. Demonstratives like ten / ta / to must agree with the noun’s gender, number, and case.
So:
- ten wiersz = this poem
- not ta wiersz
- not to wiersz
Ten means this, and tamten means that.
So in this sentence:
- ten wiersz = this poem
- tamten = that one / that poem
Polish often uses tamten to point to something more distant, either physically or in the conversation.
Because Polish can leave out a noun when it is already understood from context.
So:
- Ten wiersz jest smutniejszy niż tamten.
really means:
- Ten wiersz jest smutniejszy niż tamten wiersz.
But repeating wiersz is unnecessary, so Polish usually omits it.
This is very similar to English this poem is sadder than that one.
