Questions & Answers about Jest tu bardzo miło.
Why does the sentence use miło instead of the adjective miły?
Where is the word for "it" in this sentence?
Polish drops the subject pronoun when it is understood. In impersonal sentences describing the environment or weather, the verb jest (is) stands completely on its own to mean "it is". You do not need to add words like to or ono.
What is the difference between tu and tutaj?
There is no difference in meaning between tu and tutaj; both mean "here" and are used interchangeably. Tu is simply a shorter version that is very common in everyday speech. You could also say Jest tutaj bardzo miło.
Could I change the word order and say Tu jest bardzo miło?
Yes, Polish word order is very flexible. Tu jest bardzo miło is completely correct and natural. Placing tu right after the verb, as in the original sentence, is just another common way to phrase it, often keeping the flow of the sentence smooth.
