Questions & Answers about Mówienie po polsku jest łatwe.
Polish normally uses a noun as the subject of jest in this kind of sentence.
Mówić is the infinitive verb (to speak), while mówienie is a verbal noun (like English speaking in Speaking Polish is easy).
So:
- Mówienie po polsku jest łatwe. = Speaking Polish is easy. (noun as subject)
- Łatwo mówić po polsku. = It is easy to speak Polish. (infinitive after an adjective)
Using mówienie makes the structure parallel to English speaking as a noun.
Mówienie is a verbal noun (gerund-type noun) formed from the verb mówić.
- It names the activity: mówienie = the act of speaking.
- It behaves like a neuter noun in grammar (it declines, can take adjectives, etc.).
- That is why it can be the subject of jest and why the adjective must agree with it (see łatwe below).
