Questions & Answers about Ta aplikacja pomaga mi uczyć się polskiego.
Polish demonstratives agree with the gender of the noun:
The word aplikacja is grammatically feminine, so you must use the feminine demonstrative ta:
- ta aplikacja – this app (feminine)
- ten telefon – this phone (masculine)
- to okno – this window (neuter)
So to aplikacja is ungrammatical, because to doesn’t match the gender of aplikacja.
In Polish, most nouns ending in -a are feminine, including many loanwords:
- aplikacja (app) – feminine
- kawa (coffee) – feminine
- szkoła (school) – feminine
There are some exceptions (e.g. mężczyzna, poeta: masculine in meaning but ending in -a), but -a = feminine is a very good default rule.
So when you see aplikacja, the -a ending strongly suggests it’s feminine, which is why you say ta aplikacja, dobra aplikacja, etc.
