Questions & Answers about Půjdu zpátky do práce.
Půjdu means I will go.
It comes from the verb jít = to go (usually in the sense of one specific trip, on foot, in one direction).
This form is 1st person singular future:
- půjdu = I will go
- půjdeš = you will go
- půjde = he/she/it will go
So in this sentence, půjdu is the main verb and already tells you:
- the subject: I
- the tense: future
That is a very common question.
Many Czech verbs make the future with budu + infinitive, for example:
- budu pracovat = I will work
But jít is irregular. Its future is not normally made with budu jít. Instead, Czech uses special future forms:
- půjdu = I will go
- půjdeš = you will go
- půjde = he/she will go
So budu jít would sound unnatural in normal Czech.
