Questions & Answers about Len jest lekki.
Len is a noun. In this sentence, it is the subject of the sentence — the thing being described as lekki.
It is masculine singular in Polish.
Jest means is. It is the 3rd person singular form of być (to be).
So the structure is:
- len = subject
- jest = is
- lekki = adjective describing the subject
This is very similar to English: X is Y.
Usually, no in a normal sentence like this.
In standard Polish, with an adjective predicate such as lekki, you normally say:
- Len jest lekki.
Leaving out jest would sound incomplete in ordinary speech. You may sometimes see omission in headlines, notes, or very informal contexts, but learners should treat jest as necessary here.
