Questions & Answers about Dane potwierdzają ten fakt.

What does dane mean here, and is it singular or plural?

Here dane means data.

In Polish, dane is normally treated as a plural noun, so the verb must also be plural:

• dane potwierdzają = the data confirm
• not dane potwierdza

There is a singular form dana, but in modern everyday Polish it is rare and usually not what learners need first. In normal usage, just remember:

• te dane = this data / these data
• dane są = the data are

Also be careful: Polish data usually means date (calendar date), not data in the English sense.

Why is the verb potwierdzają in that form?

Potwierdzają is the 3rd person plural present tense of potwierdzać (to confirm).

It matches the subject dane, which is plural.

A quick comparison:

• potwierdzam = I confirm
• potwierdzasz = you confirm
• potwierdza = he/she/it confirms
• potwierdzamy = we confirm
• potwierdzacie = you (plural) confirm
• potwierdzają = they confirm

So:

• Dane potwierdzają... = The data confirm...

What case is ten fakt, and why does it look the same as the dictionary form?
